I'm buying these again. Last time I got the brass ones but i imagine its all the same. 5 stars does what it says. Works well and eliminates any ash being inhaled. Only thing I'd say is that you can't push these down into a pipe with your fingers very well. I usually use a pen but a paperclip is probably better. Just to be aware of. Also, I've read reviews for other screens that can be used a few times and these are definitely single use, so know what you're getting.
