Unfortunately I have no choice but to leave a negative review. I purchased two tempered glass Apple Watch screen protectors. I followed all instructions and still ended up with bubbling and the screen cover being unresponsive to touch. Basically it makes the watch usable. I contacted their customer service team and they told me I was at fault for how I fitted the product. They did office store credit for the other one which I have not fitted but I don’t even know if I’ll bother. It’s such a shame as I’ve use products like this before with no issue. I wish I had read some of the reviews prior to the purchase. Do not waste your time or money.
