Hello FriendsRaptas A1 worst watch ever in my life it has no good features. It look it a box on hand it very heavy compare to another smartwatch. Other Feature it has a only bluetooth and sim support are two feature which I like in it and the it support GPRS internet service. User Friendly it easy to user it has only one that feature is good. Value of money friends it totally waste of money when I brought it I am very disappoint from it. Design it has a design like a square box in hand design is the worst thing in it. Battery life it has a maximum life of 2 hrs only and it is not useful to all thankyou for reading this .????
