Hi guys myself RABIN. Today guys I want to share my point of view on bingo c6 smartwatch. I came to know about this watch online when I was looking for a smart watch. Then I ordered it.After three days it came to me. The first look was impressive. It was really a good looking watch.but when I look closely I found dents & scratches.then I put a sim card & a sd card in it. Then It showed me that this is an invalid sim.i also put another two sims but it showed me same thing.so I decided to back the watch to its seller.one thing I also noticed that it got very poor battery backup.it only run 4-5hours if you are full charged it once.ao guys I must tell you that don’t go for this watch, save your bucks it is not value for money at all.
