First I look the specs in web sits.Raptas A1 bluetooth smart watch I think it is good I because in the basis of the specs I see in the site.it has nfc, bluetooth etc.
Later I brought the watch in first week I think it is great but the screen resolution is too bad.
After 2 week I feel full of laging and bugs in the wrost watch.full of hang and its touch pad is not working properly.And wrost display I ever seen.After one month the product is dead compleatly.so dont buy the wrost product.dont waste your money for it
