Sturdy but too cool compared to the cheaper units.
These are sturdy and well put together and the longer power cord makes this appear really good. However, if the temps outside the barn drop into the 40 s or even low 50s better have a back up plan. (some of the old cheapies around) These do not put out enough heat to keep a small flock of 50 birds warm enough even though this was just inches above the birds. Even with two of these hanging above the birds we were losing birds to the cool temps and the barn was closed up.
ProsHeavy duty plastic.
ConsNot enough heat production.
