BUENAVO Fitness Tracker S2 Smart Wristband Bracelet, IP67 Waterproof Wireless Bluetooth Call Remind Auto Sleep Monitor Sport Pedometer Activity Tracker for Android iOS Phones

So in an earlier review, I reported that the tracker unit was difficult to charge. Well while using it on vacation, we only had one time of wall charger that has the USB port on the side. For some reason, this unit does not work well with this charger model. But, when we got home this weekend, we used a wall charger that has the USB port on the back end. MUCH, MUCH better results! So, this is a good tracker for the price and charges well if you have a better USB wall charger.

Without the phone, you cant see the mileage. I expected the synchronization of sms, emails and others. But only call can do the syncing. The rest none. Not so happy using it. The color of the band was not attractive comparing in the picture. The red color in the picture is very strong.

So many things wrong with this item, where do I begin? The heart rate monitor is HIGHLY inaccurate! While at the gym, my heart rate was 146 according to my trainer and a fitbit that was on my other arm for comparison, this S2 fit monitor said 92. I could feel my heart beating out of my chest but this monitor only said 92. It doesn't record sleep. Even though the watch synced to my phone, it didn't maintain records of steps taken when the app wasn't running in the background and the next day all of that information was lost.

The watch works well even during my Water Exercise Class. It is rather hard to recharge the batteries but I did figure it out so that problem has been solved. I am enjoying the watch

So far so good! Customer service has been great - whenever I had a question they have replied promptly.

I love the watch the only thing it was hard to find replacement ban

Needed something simple for my daughter. She loves this and is kicking my butt in steps taken daily. Glad to have found something that works to keep her motivated and happy!

A bit difficult to start with but has performed as advertised since then.

This fitness tracker is definitely what I needed. It's light & airy & easy to understand. Right now I have an iPhone 4 so I cannot use all the different things on this bracelet but I'm capable of using the Heart Monitor & Walking & Cycling ones. Waiting for a bargain on a LATER iPhone so I can play with the rest of the stuff.If I can use this Tracker then ANYONE can. I'm 74 yrs young & counting. Hopefully, all my walking will get me "younger" hahahhaHave already recommended this to my friends. Both the Seller & Fitness Tracker are 5 STARS in my book.Irene

Software to run this product is too old to run on new Android systems...I sent mine back

Isn't working very well. Says iv taking steps when I was sleeping . Just keeps messing up! Not pleased with it

Battery does NOT last as long as advertised and step counter has no idea what it's counting

Très bien
