Be careful!!!

I loved this product but there was one problem that caused my parents to spend FIFTY DOLLARS on! Yes, I am a kid writing this, which I know is probably strange, but let me get on with the review. This product claims that it has fourteen sport modes, but on the app AND on the watch, I only saw hiking, walking, biking, and running. Speaking of the sport modes, the product claims it is capable of going underwater, even that is supposed to be used for swimming. Having a pool I was exited about this, but wearing the watch into my pool, in the shower, and in the bath tub was a problem because after a couple of weeks, water had made itself between the screen and the actual watch. Because of this, not only had my watch broke, but I couldn’t even use the app to track my hike! I know I have said a lot, I wanted to let you all know that you should make sure whoever receives the product NOT to put it in water unless they want to spend twice the money for a watch.

Fitness tracker watch review

APP STOPPED WORKING. FIX THIS. ASAP. EVERYTHING IS BLANK FOR 5 days now. It won’t connect to watch.

Please do another bug fix update! My app is not syncing to the watch at all and says data blank!! No matter what I try. It isn’t working. My watch sitting next to it and it says watch disconnected. So I reconnect and try to synchronize. And nothing happens. Waste of money.
I’ve had this watch about a month now and it worked great at first. Now it shows sleeping at 19:33 I’m guessing that’s 19 hours and 43 min? Yesterday was 16. The app has a totally different time which is more accurate. Obviously I didn’t sleep for 19 hours. Not even two last night. It also keeps changing by itself from metric to imperial when I have imperial set. Now when I go in to check hr or bp on the watch and turn the screen on and select which one. It will start the process of testing my heart rate then shut itself off a second in so I have to start over turning screen on watch and going through each item to reach the hr or bp and do this 2-4 times before it actually will stay on and test me. Annoying. Update after a month and half the watch now stopped synchronizing to the app and won’t update the app and I can’t get it to connect.

My watch wouldn’t illuminate and display anything

I am disappointed with this Fitbit watch because after receiving it in the mail I was very excited and looking forward to using it in my exercise rituals. I followed the instructions manual to the best of my ability. I downloaded the app, scanned the barcode, fully charged the watch and paired it with my iPhone, only for it (the watch) to not display anything at all. The screen shows a dim blue light that goes on and off which is how I know that it’s connected with the phone. but it stays blank the entire time. The owners manual is not very helpful at ALL! There’s no on and off button on it, so I’ve spent hours trying to figure it out something, I’ve contacted the site, hoped that it would eventually just kick in on its own and start working, but to no avail. I don’t know if it’s me not knowing how to operate it correctly or if it’s just that I got a defective product. It’s been very frustrating seeing that this is my first Fitbit purchase. Now I’m a little leery about purchasing another one .
