I have one of the originals without the "stop" and it works great for me (just used it yesterday!!). What works best for me is to make the bowel relatively short on the inside then use the Butt Out at/in the "end"!
Yep they work great. I used to carry it in my back pocket then..... LOL. Been using it for years. I'll never not. Wait, it's good, I like it and it works. Better get a couple extra because they'll stop making it!!!
