...you need the BG-E3 battery grip (or equivalent) in order to use this hand strap. Otherwise, this is a good product. It's very comfortable and adjusts easily. My only complaint is that the instructions for this item are included with the BG-E3 and NOT with the E-1. This doesn't make much sense, but a quick Google search can remedy this.
works well with the battery grip. camera feels secure.
Not very well padded, but still comfortable
Great on a Canon digital rebel XTi with an Opteka battery grip. Supports the camera, battery grip and a 70-300 lens in one hand. My only complaint is that there is no instructions on how to attach it, and its not that easy...just follow the instructions from here: http://photography-on-the.net/forum/showthread.php?t=57766
I works well, just could be designed to sit back farther on the wrist.
Both of my camera bodies have the E1! The strap is very comfortable and I love the fact that I don't need to have a strap over my shoulder!
I have this strap on 3 different cameras. I bought my first one to keep the camera secure when not using a neck strap. What I found out is that it's even better at taking the load off your hand during a prolonged walk. You don't have to grip the camera much, so your hand can relax. With your palm pointed down the strap rests on the back of your hand. I find the wrist/arm muscles that support the camera this way don't tire as easily as the hand/wrist muscles that support the camera without the strap. Good for taking a load off during a walk-around. The strap does take some effort to install the first time you do it. For non-pro camera bodies, the instructions are found with the battery grip instructions and are not included in the hand strap packaging.
Provides a firm grip for the Rebel XTi which is small for my hand even with the motor drive grip. Helps keep the camera in your hands. I feel more comfortable shooting over water or in high places.

Gives me a secure grip on my Canon cameras under varying conditions. Would not be without this strap.
A great comfortable feel in use with the battery griip on my 20D. I feel strange without it.
This is another great accessory by Canon. Perfect for any EOS camera with battery grip. I use a 20D with the vertical battery grip. THIS PRODUCT WORKS GREAT!!!
