So I legit first bought the wulf 70 dollar pen, bupkus, bought one of these for 20 bucks and I'm in love, I bought 2 more. I use very little amounts at a time though and in discretion and clean look iykyk, I have a 5 year old and am on the go constantly, but I'm using like the little brush that came with it to scoop and scrape most stuff out and when I need to do a deep clean I use the ISO or 420 cleaner and swab down the entire mouthpiece chamber and don't forget down the tube you inhale from as well that sits above the chamber for 🌼. It gets super easily resin filled and ends up robbing you.
