Here's the lowdown Purchased January 10, 2021. Received in a few weeks from a fulfillment center. No information about company's physical address. My actual recent experience has been very disappointing : 1) The watch and 2 watchband pieces constantly disconnected 2) The watchband is way too big for me when I could occasionally get it together without falling apart. Even using the last hole in the strap, the watch hung too loose on my wrist to function. I tried sliding the watch up my arm when it was holding together, and one piece of the band or the other disconnected. 3) The information / operating sheet was on a tiny piece of paper with EXTREMELY SMALL print that I, with 20/20 vision, had trouble reading even with a very strong magnifying glass. 4) Because of the preceding problems, I was unable to get any meaningful data from this watch with alleged health data. I would very much like to return this item, but am having difficulty getting a response from freesmartband.com

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.

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.

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.

Bought this watch not realising needed… Bought this watch not realising needed special charger. Ordered charger and 3 weeks later received an mini electric toothbrush. Tried to resolve this but no answers, NOT IMPRESSED. Will not be buying from here again
