No disrespect to OP, but I just wanted to point out as someone who won a ROGBID Smartwatch before, the one I got, the S2 model stopped functioning within a matter of 2-3 days. It worked at first and I was able to connect it to my phone but it was very flimsy to use. I would press the button to turn it on and I could use it for a bit but it would quickly turn back off and then remain like that until it would turn back on at random. This ultimately stopped in the next few days and I could not use it at all. Very poor prize and that junk is definitely not worth $10 let alone a RRP of $80.
