Nikon BM-10 Compatible Snap-on Hard Screen Protector Cover for Nikon D90

Pros: cheap and functional replacement for the original.
I sometimes abuse my D90 and get those protectors scratched. For this price I feel better about it and just replace it with a new one.

Cons: It doesnt fit as good as the original. Its easy to push it off the D90 body. Not a major problem though.
My last one fell a few hundred meters down a mountain.

Other: typical use&abuse item for little money

Pros: Nikon BM-10 Hard Screen Protector Cover:
It has an Excellent Price
Besides Nikon d90 and d5000 It Works on Nikon D3100 (does not fit perfectly but it is not a big deal)
it is Easy to put in and out
Looks as the genuine one
Doesnot affect quality on Preview pictures on camera

Cons: Mine came with scratchs
Feels that can easily break
It is not that hard cover

Other: It as an excellent option to protect you screen, it works on Nikon D3100 (no perfectly but almost) and for that price totally deserves a chance.

Pros: Basically the same as the original accessory, few people will find the difference. It may be a little lighter than the original protector, but does not lose consistency or transparency.

Cons: Comes unpacked, which can cause unwanted scratches and marks. Should be delivered with special packaging.

Other: All camera owners should have one of these protectors for keeping the original screen without marks or defects.

Pros: In fact, I have never tried the original nikon LCD protector cover. Although my camera is not the D90 (it is a D3100), I bought this product based on a previous review, which says that it fits the D3100 (although not perfectly). It happens that this cover fits very well. The product is cheap enough and functional to both D3100 and D90. I got surprised that this cover does not affect the quality on preview pictures on camera.

Cons: No cons at all.

Other: It is a good option to protect you screen, and it works on Nikon D3100 (no perfectly but almost) and for that price totally deserves a chance.
