I seriously cannot complain about these little units. For $50 to $90 each, they were workhorses, especially when wired with PoE. Their wifi matrix antenna left a LOT to be desired, but the video quality was excellent, and the firmware was top-notch. My kitchen unit just failed, so I took one of the old spare units out to replace it. Nope, it's not doing too well, either. I just bit the bullet and ordered another Amcrest IP4M-1051B 'renewed' unit to replace it. Better picture, better wifi, and great price; $67 before tax, a $10 break from a "factory new" unit.
