AMAZING Smart Watch, excellent value & quality
This Tozo S2 Pro Smart Watch is truly AMAZING !The quality and feel is really good, the screen is very clear and bright.The watch is full of great features, with a very easy to use app, where you can change lots of settings, add new watch face designs, set up Amazon Alexa.The Alexa feature is very useful, and it actually worked very well, I tried it to turn on and off lots of my Alexa controlled devices, and it worked perfectly.This S2 Pro is too good for the money, if it was one hundred and fifty pounds, it would still be good value in my opinion.I have many Tozo products, and all of them are great quality and value.If you are after a very good Smart Watch at a very affordable price, I highly recommend this Tozo S2 Pro.

Surprising amount of battery life in a really functional low cost smart watch!
I’ve not worn a watch for a few years now, the last one was one of the very early android smart watches, and aside from some comfort issues at the time, my biggest issue was the battery life. As much as I wanted to use it, it not managing 24h on a charge and I just kept not bothering re-charging it I just stopped using watches… Recently I saw this TOZO watch, the main things I was interested in were some of the monitoring features, heart rate, sleep, etc… And the price was decent, I didn’t expect to use it full time but decided to just get one and try at least.I’ve now been using this watch for around 3 weeks and am surprised at the battery lasting more than 8 full days each time with a small amount still left. Charging is quick and easy with the magnetic connector and low hassle with only having to do it roughly once a week or so.Some of the smart functions are decent even if simplified to what I’ve tried before, having Alexa on there is a slight gimmick ‘for me’ as I already have Alexa dots around the house but I’m still impressed it’s on there.The strap is comfortable, I’m not fidgeting with it and mostly don’t feel the watch is there. Which has changed my view on me never using watches again. The monitoring appears to be good (I have no way to know how accurate it is, but seems good.The sleep tracker works ok, I’ve seen it miss a couple of times when I woke up but overall seems good enough to give me an idea of my sleep pattern.Overall the functionality and battery life you get yet such a low price is impressive enough to make me do a review 😀

Good Budget Smart Watch
Got for my 10 year old daughter, who has been using it most days this year, she loves wearing the watch and does so regularly. It is a fairly priced budget level smart watch that she uses to track her steps mostly and sometimes sleep. It can miscount steps (as does my Garmin watch) mistaking arm movements for steps. I dislike the mobile phone app to be fair, and it seems to want a lot of access permissions.I asked her for a review, as below….The Tozo watch is good,BATTERY.The battery on the watch is quite good, it lasts up to about 3-4 days and charges SUPER quickly it takes roughly 1:00 hour to charge up.It also has an app that finds ur phone for u, ur phone rings and u find it simple as.I love the fact it has soooo many little app things it’s got stuff like:.heart rating.blood oxygen.breath training.stopwatch.alarms.timerAnd so far, I’ve had no issues with it,Itâs a great watch.ððððð

Smooth, Elegant and Responsive
Received the watch today, and it feels so comfortable. The straps are a silicone rubber and feel really gentle. They can be installed and removed very easy with a small clip pin which is a thoughtful addition.First impressions are that the watch is responsive. No lag, heart beat appears to be accurate as are the step counters (when compared against my Samsung Gear).Setup was super simple, I didn’t even need to get the manual out, simple pairing with my android. No headache at all.The charger is brilliant, it’s a magnetic cable which almost sucls onto the back of the watch (only goes on one way).. that’s very cool.I’m impressed with the watch faces, quite a few to choose from.The display is clear and screen is a good size. I was a bit worried about getting the 44mm version with skinny wrists but I’m glad I did because it looks just right.I can’t comment much about battery life right now but I and hoping that it lasts at least a full day with some play. I’ve also not set up Alexa because I prefer Google Assistant. It’s a shame that the watch doesn’t support Google (yet!) Hopefully software updates will fix this.Ultimately, this is for my dad who is not very techy and for the price I am actually really impressed. It seems to be great value for money. I went for Tozo because I’ve used their buds in the past which are amazing and I know that their support is brilliant too… It was a gamble but I’m really happy!!Well done Tozo!!

Really good for the price
A fab buy for the price. I wish it would syn faster and the sleep function is pretty hit and miss. But forcounting steps, knowing that time and comfortable to wear I would highly recommend this watch

My conclusion about this watch after a year+ of use:This is a great simple watch that TELLS TIME, and other very helpful things. It didn’t break my bank. It’s stylish, not too big for my small wrist and in the way I use it, has exceptional battery life.Read more to see a few specific reasons why I LOVE MY WATCH. ð¥°So, I read reviews. I also write reviews. I agree that this watch is not in the ball park with a Samsung or Apple watch.However, for those of us that don’t need or want to spend that much money or need the bells and whistles on the high end brands, this watch is just right.I don’t need to make calls on my wrist for everyone to hear. However, I do want to see my messages and to see who is calling and be able to decline calls. This watch does that very well.I do like keeping count of my steps. But, I don’t feel the need to use all workouts it offers. I use an app on my for that.I love being able to control my music and volume without having to get my phone out.So, I maybe don’t use everything this watch is capable of doing. But, what I do use works great and is consistent and has been for over a year.Some have complained about the battery. COME ON! If everything on the watch is in the on mode, the battery WILL DRAIN! Only using what I need, after over a year of use, I don’t even charge once a week. It’s comfortable and so I just leave it on.If I could leave a message about this watch for the Seller I’d say, please don’t stop making this watch. I love the size and have bought many bands to go with it. In fact, if ever this one breaks, I plan on replacing it it with the exact same one if possible.Thanks for reading!!!

I had a Fitbit and it broke during warranty and was replaced, then the 2nd one broke shortly after warranty expiration again. I priced a newer version and it was almost 2 bills. Then I searched further on Amazon and found this deal. This watch also came at the time with a 10% off coupon making it ultra affordable. I decided to take a chance and so glad that I did. The display is large which is great if you wear glasses for reading like I do. The watch face download selection is great, I keep putting new ones on to try but ultimately revert to the large format numbers with the steps and everting on the front. The battery life is also strong as I am running my Gmail and telephone call notification through it daily. I have to recharge about every 4-5 days which is really good. It is highly waterproof. I am in FL and have a pool and garden and have 3 grandkids my hands are always in water. My husband just ordered one in black for him. You will love this choice. I think it would make a nice gift for a birthday or holiday present to someone who never had a smart watch. I have to say this was a great purchase.

I have an Apple Watch. This is no Apple Watch. Butttt it doesnât cost what an Apple Watch does. Itâs a GREAT starter watch. My hubs and I both tried it. Hubs felt it was a bit small screen size for his huge hands. He liked the features & functions though. He wore it to work a week. I wore it a week as well. For the money itâs great for the price! I bought it to track my heart rate and sleep while my Apple Watch charges at night. It works great for this purpose. I would be great for a teenager or someone wanting to try a smart watch. The app is pretty basic but is okay. The watch screen is pretty responsive and bright. I like how the watch band has several holes for adjustment. More then most watch bands. My 6 year old grandson can fit it as well as my man sized hubs. I didnât have much faith in the blood pressure readings. But itâs pretty spot on with my home cuff thatâs been calibrated by a professional. I have POTS so wear a smart watch to monitor my heart rate. Also for convenience of course too. I have to monitor my blood pressure as I struggle with low blood pressure. So I have my blood pressure cuffs professionally calibrated. I have a small cuff I carry with me at all times. This watch was really close with the blood pressure for both me and my hubs about 90% or the time. BUT DO NOT a rely on it for that! ALWAYS take your reading with a blood pressure cuff thatâs accurate. But it did help give me an idea what my numbers was. I love that about it! I also love sleep tracking. The heart rate was always spot on when checker with my other devices. Those too are professionally calibrated. The only time the heart rate gave a wonky reading was a couple times I didnât have the band adjusted right. After readjusting it it then read correctly. So be sure you have a good fit for the sensors to read properly. That was my main goal with it was the sleep tracking and it does that well! I do not like the wonky charger thatâs specific to this brand. I donât like the short cord that comes with it. You can buy other cords but itâs hard to find long ones for this watch. That honestly is about my only complaint with it. The battery life is amazing! It lasted me 6 days and hubs 5. Thatâs pretty awesome! All in all for the price itâs a great watch!

Streamlined easy setup instructions and navigation of the app: once fully charged, the watch prompts you to download the apps to your phone. Open the app, ‘Scan QR Code’ (on the watch screen) then can add the device — this is really SUPER convenient! Bluetooth connection is effortless. From the “Edit Card’ of the ‘Home’ screen of the app, you can add/enable/disable the gadgets on top of those default ones. Navigate to ‘Exercise’ screen then you can start GPS enabled Hiking, Indoor/Outdoor exercises; switch to ‘Device’ screen, you will get the set up for enable/disable Notifications from your phone like email, SMS, messaging, phone calls, etc., and config for ‘Alarm clock’, ‘Health’, AND tons of Watch Face selections for download; go to the last screen ‘My’, you will get all your exercises and health data, goals, preferences, and other settings specific to youFunctions: don’t want to repeat what’s been already mentioned in the product website, and truly they are all in this smartwatch — a ton, and fairly comprehensively a health tracker that can fit into a watch, I can’t think of if anything else needed. For Heart Rate monitoring, I chose ‘Intelligent monitoring’ vs ‘Real-time monitoring’ — the latter will consume more battery and not needed for me, and I also enabled ‘High heart rate alert’Anything could be a bit better, at least for me: Blood Oxygen (spO2) would be nice if can be directly navigate on the watch the same way as Heart Beat or Stress — currently you will need to go to ‘Function’ (press the button of the watch) in order to get to it. Also, battery wise, seemed to be like what the product says 7-10 days, but the ‘wrist awake’ and touch screen seemed not as responsive when the battery is about 20% left, so I rated the battery life as four starts. I haven’t got to try the ‘Sleep tracking’ yet but will see how it goes.All in all, I gave it a 5-star rating – can’t be wrong to buy this smart watch with such a great price! I bought my Fitbit wristband for $99 each for myself and my wife just about 2 years ago — that just CANNOT be compared with this smart watch. As a matter of fact I like it a lot so that I just got one also for my wife — it comes with rose gold wrist band, the model is S2, my black wrist band is S2 Pro, unsure what’s the difference but I tried out all the functions, seemed to be the same

Ta padre. Le puedes cambiar el salva pantallas al reloj. Lo unico que no me gusta es que hay que tenerlo demasiado apretado para que lea tus signos.
