Excellent product. Bought the 44mm for me and the 40mm for my spouse. I have been using them for about 7 months now. Easily applied to the watch face with good instructions. The protector sort of clicks on with a strong plastic frame. My spouse cracked her screen protector against a concrete block. While the front of the screen protector cracked the watch was fine. Contacted the flolab automated service about their lifetime protection. The protector was replaced the same day with no issues,just had pay for shipping..$8....oh and it arrived in 6 days!
Overall great product and great company that stands behind their product.
Some have noted that you get moisture under the screen and the protector fails to then work (touch screen does not function). This is absolutely true..however just take the screen protector off (just take it off by unclipping the non crown side and pulling straight up). Clean the watch face and screen protector and put it back on...voila..good as new. I have done this numerous times as I run triathlons , this water under the protector is not an issue.
Keep up the good work flolab!
