Update.
We ended up ordering some of these. I used them on cattle that were around 450-500lbs.
They were super easy to use and apply. The sacks started to dry in in days, and fell off with in 4 weeks.
I would recommend these to everyone, we will definitely be ordering again.
I'm curious to know if anyone out there has tried them actually? And what was your experience?
I called them and the guy said they haven't any swelling issues other than the normal swelling when you band, he said depending on the size it would take about a few weeks for them to actually fall off...
