I have had the Whitestone Dome inner (and outer for that matter) on my Fold 3 for months now and the WSD Inner one is SO MUCH BETTER than the stock on and my brother has tried a few other ones before installing the WSD on his inner.I peeled mine off yesterday and fitted the whitestone dome one, went on perfectly much to my surprise, feels great, my mate who has a fold as well commented that the screen looks sharper than his with the original one on.
The BIGGEST issue with all of the others he tried was the same as the stock one:
"The adhesive was not strong enough to keep hold after use, the WSD Film has so much of a stronger bond that it will not peel up easy, if at all."
There is a reason the install kit includes a removal kit as well, it's hard to peel off (I peeled one off a dead Fold 3 and without the removal kit, it was hard).
The overall feel is nice but as you stated, the clarity and the fact that it resist fingerprints, smudges and dust better than the stock keeps me from having to clean it as much and it just looks better overall.
