Don't like them much. Support peices at front of calf's legs get in the way. Aren't good unless calves are very gentle and then you don't really need a chute at all in my opinion.
They do work well for the "seasoned" calf that is calm and used to standing. Especially at shows where you stall and fit at your trailer they work fine. But they are not worth a damn with breaking cattle in ...
New to showing need help with show stick
