I recently returned from an overseas trip where we were riding in boats and jiggly buses extensively. My wife loves her D7000 and I had applied glass protectors to all the LCD's on our various cameras. The D7000 shifted during a bus trip and came into contact with a tripod, with resulting fracture of the applied glass protector. Luckily, there was no damage to the underlying camera LCD. I think I'll use these again. Very cheap insurance.
I used the GGS glass stick-ons for the rear and top LCD's on my D7000 and they were so well made they looked like OEM product. MILES ahead of the plastic snap-on, AND the top LCD was protected too! Glad yours came through OK.
I'm really not careless, just kind of unlucky. I've been saved by three broken GGS LCD protectors over the last few years. At about 8 bucks apiece, a real bargain. I but two or three at a time, just in the hopes that having them on the shelf will counteract Murphy's Rule.
If you're really not careless, that seems to be an extremely high accident rate. We rarely hear of broken LCDs and even more rarely hear of multiple breakage events from the same person - in fact, I can't recall ever hearing of it.
That has me wondering whether the LCD protectors have really saved you or if the protectors themselves are thin, inexpensive glass mounted in an exposed position that makes them much more vulnerable to breakage than the actual LCD.
I don't use protectors other than the plastic ones that have come with my cameras. I also don't baby my gear and I've never broken an LCD - not on the Nikons at least. I did break one on a small Panasonic once that was rattling around unprotected in a back pack with other unprotected equipment. I earned that breakage and am a tad more cautious now. I doubt if anything would have saved that LCD from the abuse I heaped on it.
I was saved by a GGS protector on the rear screen of my D700 a couple of years ago during a trip to Europe. I use them on all my cameras now. I had been using a vest to carry my camera and lens (unmounted), and obviously bumped it against something. I don't vest carry now either. Just use a small padded bag that the camera fits in and can be easily drawn or re-stowed. Works for me.
GGS and Giottos are the two brands I strongly recommend. Excellent transparency factors, no color shifting (key on the rear LCD!) and as you can see, it works.
As for the folks who don't think it happens (or happens too often), it doesn't take a catastrophic hit for LCD protectors to earn their keep. If you really use your camera, the back and top eventually get scratched and dinged over time. Personally, a 20 buck protector beats having to keep seeing an annoying scratch in the wrong place every time I preview a photo or check the top-deck display for a setting. Every camera I've had or own now has a GGS and Giottos. When I sell off the camera for an upgrade, I'm actually quite heartened that the next owner is getting the benefit.
The GSS on the rear LCD of my D7100 is fantastic (as they were on my previous cameras) - sturdy and incredibly difficult to scratch. However, I've broken two protectors on the top LCD (unlike my previous cameras). I find them fragile and prone to shattering under even the slightest stress. I won't install top GSS glass again.
