Love my little Van Dyke bird flesher that's about 40 years old...never had an issue. The motor will stop if you apply too much pressure. There is a learning curve on wheeling a bird. If I think there is a chance a bird isn't fleshed properly, I insert a paper towel around the body prior to sewing up. Any lingering fat will bleed into the paper towel, rather than out of the skin and onto the plumage.
