Solid purchase, Highly recommend
Having been a loyal 5 wearer I was excited to make the move to the 8 and I was certainly not disappointed. From the first moment I put it on I noticed that it was lighter and had a better fit on my wrist. The tended to roll toward the outer part of my wrist and I always felt as if I was centering it. Not the case here, it sits right where it should. The screen is bright and clear and it reacts super fast. With smart switch there was hardly any set up. I have had it for a bit and I do not regret my purchase for a minute. This version also give you more ability to use it... that is Gemini is on board and with a press of the side button is ready to assist, texts and emails are much eaiser and all.of the added health functions are amazing! The battery is also much better than my older model. This was a solid purchase and I highly recommend it, especially if you have an older Galaxy watch like I did.
