Customer Review: Works okay after a little tweaking to make the charge work. Only works after some fidgeting and properly placed tape to stay in place. Save the time and tape and get the brand name.
Customer Review: I use my Canon D30 for macro photography and before I got this remote switch I ended up with a lot of blurred photos; now I have better control and fewer blurry shots. It also works with my autofocus feature. It has made me a better photographer.
Customer Review: For a piece of plastic this thing is amazing. I've used it on my 40D for about a month now. Lack of an off button is a little hard to get used to you but I learned to just think of it like a wristwatch or something where the battery is always going. I recommend this product.
