Challenger Smart Band CHG304E Challenger Smart Band CHG304E. The fact you can't find them on Google tells you they are hiding for a reason. POS doesn't even see Bluetooth let alone connect. Zero support. AVOID.

Customer Service (Andreah) is incredible! I received my first watch and it didn't hold its charge. I contacted customer service and Andreah was incredibly helpful. She sent me a replacement watch. I haven't received it yet so I'll see how this one holds the charge. So far I haven't had much experience with the watch but Andreah, their customer service rep. is awesome.

I am giving 5 stars for the customer service rep I am giving 5 stars for the customer service I recieved. The watches would get 4 . They are very difficult to figure out (took me 4 days to get them connected to my phone and the app). I ordered 4 watches and 1 won't hold more than 2 bars worth of charge. After contacting customer service they are replacing the watch that won't hold a charge and I was finally able to get them to connect to the app. The customer service rep was very quick to respond and helpful with her responses.

I am not impressed with this watch I am not impressed with this watch. Yes I know I only paid for shipping, but it is less than I expected. The settings in the app are so limited. The app has a lot to be redone. It is more complicated to see the recorded data. I wanted a tracker for steps, sleep, calories burned, heart rate, water intake. The battery has only last just over 1 day before shutting off without warning I don't care about the running or situps. I will be using my Fitbit again

Not Suitable for Samsung Phones Received my order however unable to connect.Used the tutorial kept on saying disconnected.Then come to find out does not connect to Samsung phones.Does not state that anywhere in ad so wasted my money.Requested a refund but appear to be making excuses.So if you have a Samsung phone not compatible.
