I bought a few (10) since they were cheap on wish.com rolling one up was not easy. I eventually figured out how to do it though. Anyhow I really like them and can see me continuing to do that going forward. I have a couple jars in my garage with roaches. Lots of them and am was collecting them and one day will burn them in a wood stove. First thing I noticed about the glass tips is there is NO waste. Smoke it all the way to the end. Also seems to be smoother till you get near the end of the joint. Then its a wee bit stronger.
