Hello guys, I am Lorence and I have a purchased a smart watch namely A1 which gives vey awesome look amd feel. But only demerit is its battery backup, it hardly works for 20 to 30 mins while installing sim card and normally witout sim card it fluently works for 40 to 50 mins. But on more cons is its touch screen, sometimes it doesn't respond to touch which makes me totally hate it. But it is very stylish with awesome colour. It too have a front facing selfie camera and we can easily capture some important moments. We can easily connect it with our phone via bluetooth and we can read and react to our modifications and incoming calls too. Memory card and sim card can directly be installed easily which will improve its performance. Over all it is a good product.
