Okay, I didn't do enough homework and my expectations were probably a bit too high. However, my rating would be higher ON SPARKFUN if they had done two things. 1) Include the $0.10 lens focusing tool in the package, and 2) provided some information on this product page about how blind this camera is in the dark.

The lens is a fixed focus lens that comes set at some distance. If you don't like where it is set, you need the lens focusing tool, a little plastic ring, to set the focus. Yes you can do it with some needle nose, but it is a pain trying to get them on the lens, not tear it up, keep your hand out of the way, and look at your monitor all at the same time. Probably costs a penny to make the tool.

You can see better in the dark than this camera. Don't think the NoIR version is any better, it isn't. So it isn't going to be a survellience camera without a streetlight.

Other than my gripes, it is a nice little camera that makes a sweet web cam when paired with the Pi Zero W and the Pi zero case with the camera top.
