So far.
It may not be the best one on the market, but for $80, I had to try it. Resolution is fair, not high-def by any means. Has a weird issue of re-booting for no reason and going back to a home position. Not a problem for me, since I'm not using it for security. Others are complaining about it though.
Wireless works fine for me, but I'll be running a LAN cable to it when I place it on the mast later.
No Zoom, but the Pan/Tilt works well. There's a bit of a color issue, not sure how to describe it. Colors seem washed out unless you play with the Brightness and Contrast. If you hit an area that is part bright sun, part shadows, the image gets overdriven to just a dark and light area, with little detail. Move to either the sun or shadows and the image corrects.
On a limited budget, it's worth the $80 easily. I'd go with a $500 camera if I could afford it.
One thing this does that I haven't seen on the more expensive units is that it tilts above or below 90° depending on how you have it mounted. Mine is upside down and I can look above the horizon towards the sky at clouds and approaching storms. I mounted it that way so I could look straight down around my property also. On a previous system where I worked, the $1100 camera could only tilt up to about 80° or so and you couldn't even look straight out to the horizon.
