Summary: Good but ...

Comment: Perfect match to the camera, but the eye cup keeps falling off. I have a difficult time keeping it locked on, especially when taking in and out of the bag on the fly.

Other than that, it is perfect.

Summary: At least this isn't a stock item

Comment: It does extend the eyepiece, but at a huge price. The viewing is far worse than the stock unit and in my opinion not worth the purchase.

Summary: Great Product

Comment: I would heartily recommend this product to everyone who has a Canon camera. It it a wonderful addition to my camera.

Summary: Necessary!

Comment: I wish this had been included with the original purchase of the camera. It makes using the viewfinder much easier and more comfortable.

Summary: Works great... if you rip out the lenses! Grab a screwdriver!

Comment: I noticed this product was getting mixed reviews... it was either lauded for keeping one's nose off the LCD, or reviled for shrinking the viewfinder's image. For those of you not familiar with this product, it inexplicably shrinks the viewable image in the viewfinder for seemingly no good reason. The instruction manual states "This will INCREASE the viewfinder image by 0.5"! Hmmm... when has cutting something in half been considered an increase?!?!

Anyway, I found some people recommending modification of the product to make it more ideal and functional, and that's exactly what I did. I took a tiny Phillips head screwdriver, took the eyepiece extender apart, and removed the 2 plastic lenses. Once reassembled (its really easy, don't be afraid), it did, in fact, keep my nose off the LCD and I can still see the viewfinder as it were before, mostly. I wear glasses and found it necessary to adjust the diopter dial to get the best focus (no small feat as this device covers the diopter dial!).

Overall, if you're willing to put some work into it, this product works. Given what one has to do to make it work the way it should, however, it should only cost $5.
