Query: It Sucks!

I bought this remote for my InFocus 70+ projector. It never worked. The company told me to keep it and keep trying to get it to work. First they told me to change the batteries. I changed them 10 times. Then they told me to clean the LED's to make sure they weren't dirty. That didn't work. Then they told me to stand directly in front or behind the projector. That didn't work. I kept telling them it wouldn't work. The only thing that worked was the power button - it does turn the projector on and off. Then they told me to contact InFocus to get a software upgrade. It doesn't exist for Windows 7. This projector is old and they did not have any updates beyond Windows XT. After the return window had passed, they wouldn't take the product back because it was too late to return it. That sucks because the product NEVER worked but they insisted I keep it and keep trying until I could not longer return it. DO NOT buy this product.
