Works good last long time. Unless a cow steps on it.
Great product. Just what it says it is. Only problem was that they were out of stock when I ordered them, and they took over a week to ship it to me.
This is really a review for a used shell. Hamby was out of new shells and sent a used one in perfect condition. I would not have known, but they also sent a very nice free gift to more than make up the difference. Thanks, Hamby's, for the great service!
