Summary: A decent webcam for under 20 bucks? Really? Really. I get a better picture than most people using built in cameras or other more expensive models. It has a manual focus which is great for focusing on what you want to, not on what the camera thinks you want. Look no further. This is a great little camera.
Summary: This item is by far not the best you can buy. However, if you are looking for the best quality and you aren't spending more then you are an idiot. It works and is easy to use. The lights are very nice for using the product in the dark. They don't shine bright enough to bother you if you are looking at the screen. The clip worked well. The video quality was very acceptable. If you are looking for value webcams, this one should be pretty high on your list.
Summary: I was looking for an inexpensive (i.e., semi-expendable) webcam to monitor a remote-control telescope. I wanted to make sure it didn't do something funny like end up pointed at the ground. The Hercules cost $8 and does a fine job. The software was easy to install on Win 7, and the first thing it did was ask to update itself to the current version.
Summary: I got this guy for free as bundled promo bonus from another website. From what I can tell, it looks just as good as my old MS VX-3000 and even records video at a higher resolution as well. Since it was a free giveaway, I was expecting this thing to be on par with the cheap $25 RadioShack webcam from 8 years ago that I have lying around as a spare, which is to say, awful.
Summary: I have read that some people don't like the software included with the camera. Well, if you don't like the software then don't install it. I have an HP laptop where the built in camera drivers keep disappearing and I got tired of re-installing them, if I could find them. So I bought this camera, clipped it to the screen of my laptop, plugged it into a USB port and it worked. I didn't install the drivers, they installed themselves.
