I killed three deer with them last year, and yes the deer bled like crazy but they are essentially a one time broadhead and then you have to replace the blades at a minimum. I had one of them bend at the hosel fairly badly. They do the job if you are in to dropping $10 every shot and not concerned about reusing them. IMO there are a lot better broadheads on the market. Consistency shouldn't be an issue if your bow is tuned properly so there isn't alot of value in their claim of flying just like field tips.
