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

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.

A friended at my church introduce me to… Befriended my church introduce me to this watch. I had Kobe born of the issues I had was a low O2. I ordered two watches with two day shipping. The Watchers took two and a half months to arrive. I emailed many times asking for a refund for for the extended shipping fee to be returned I don't know what answer saying there had been some type of storm or something they were sorry they were late. Never was my concern which is the extra money I paid addressed. I'm also a former eBay seller, have connections with wholesale, the watches are worth 2 bucks if you buy them in bulk. I knew that when I ordered it thought I was getting you something I could use as a medical tool in a timely manner, all of my reasons for getting it were contradicted by their actions. For $65 when can get a branded sports band with all the same features and extremely more durable!!!

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.

Nothing was ever said about the app… Nothing was ever said about the app that allows this watch to work, the app doesn't work properly judging by all the negative feedback it has received. What good is a watch that requires an app to be able to get all of the functions to work when the app doesn't work! Might be a good idea to get the app working properly before anymore watches are sold!! I intend to post this same review on the Facebook page where they're being sold to warn people about this before they waste $15.00 of their hard earned money on a useless piece of crap!
