The tool works fine, but it's not real big; don't do what I did and wait too long before trying to tackle a beefy calf. Otherwise, it works great and is easy to use.

I bought the economy model because I have only one goat to band. Unfortunately the bander does not open far enough to band a 10 week old Boer goat. The max opening dimensions are: top 1.75', bottom 1.5 " and 1.25" on both sides. The tool seems to work OK but you need to keep those dimensions in mind and get the job done earlier. It would be helpful if the manufacturer would include the maximum opening dimensions on the packaging. I'll try the better model from TSC as the QA mentions it opens to max 2.5"
