Customer Reviews for ZAGG - Screen Protector FIT Samsung Galaxy S21 Ultra 5G GlassFusion with D3O - Clear

I am a minimalist, which is why I purchased a 40mm Apple Watch. Since my priority is a small, sleek watch, the last thing I want is a big, bulky screen protector or bumper shroud. I have been on a quest to find the most minimal screen protector that provides maximum protection. Initially, I found a well-fitting, inexpensive glass protector I liked, but it was so fragile that I shattered four in a month and a half. I then found an expensive, VERY sturdy plastic screen protector, but it was too thick, with rough edges, and peeled off in the first week. After finally finding and using the InvisibleShield (it's in the name!) GlassFusion+ screen protector, I have realized it's the perfect FUSION (pun intended) of the two aforementioned protectors. It is the perfect fit, with tapered edges that so far haven't caught on anything, and is a mix of glass and plastic, which leads me to assume it is less likely to shatter.
I would recommend this to a friend!

Bad product doesn’t wet out. Took off and tossed it away.
No, I would not recommend this to a friend.

My invisible shield did not work. I had bubbles under all four corners.
I would recommend this to a friend!

If this works as well as the Zagg screen protector for my iPhone, which has fallen on concrete several times and still has no scratches, this GlassFusion+ Screen Protector for Apple Watch will prove to be a worthwhile investment!
I would recommend this to a friend!
