Hello and welcome to the forums @Porus
There is a huge ChargeHR area with articles and an owner's manual if you click here.
There is a sticker on the face of the device, so be sure to pull it off before setting it up.
As for purchasing it on eBay, be sure the seller is an authorized retailer of Fitbit products. Only those devices bought from an authorized retailer (such as Best Buy, Target and others) carry with them the 365 day warranty. Many people buying devices on eBay, even unopened and new, have found there is no warranty since it wasn't from one of the Fitbit authorized retailers.-
I'm moving this over to the iOS area, so you can get additional help for your phone.
Let us know how things go for you.
