Made it hard to use the camera.
I use a 400D with a 100-400 IS lens, for wildlife photography. Walking through the woods for deer in the winter while trying to keep the snow off my camera isn't fun, however, this Rain sleeve did the job. Is it perfect, no, I had to tape the bag to the hood of my camera to give it a good solid seal. However, the rest of the rain sleeve kept my camera nice and dry and still allowed me to have access to all of my controls. Would I use in a downpour, no, in a light rain or drizzle, or while moving to drier quarters, YES. You can not get better protection for the money.
Very good to have, for the price. Though I am against the use of plastics, as they build up on the planet, I will tape the holes in this cover and reuse. It saved my camera in some very rainy, sandy, dusty and salty situations on a trip to Costa Rica.
Not bad for it's price. Works.
Nice, simple product. No problems when I used it in a downpour.
