My favorite is the Genius Pipe. This pipe is small, has a compact design, and is portable. That's why it is one of my favorite devices. You can take it anywhere and smoke whenever you want. I have already changed a lot of pipes but this one I use oftener than others. Also, it is easy to clean it. It has a water filtration system to clean the smoke and cool it down. I have found a good review athttps://askgrowers.com/blog/genius-pipe-review-better-than-other-pipes. I think it can be a good decision for beginners.
