So I’ve purchased unbreakable silicone pieces before that have an opening on them for easier cleaning, and it constantly leaked gross bong water all over me, but this one is great! The opening is above where the water line sits, so no leaks, and the way the opening is designed to put the bong back together makes a strong seal! The piece and the mini down stem are all unbreakable and easy to just shove in a bag and go. When I need to clean it, i just open it at the middle and pour the water out, and then I have basically full access to the whole inside. The only thing is that silicone bongs hold the smell a lot more than glass obviously, but that’s not just this one. Honestly my go-to travel piece now :) canna style has been the only place i buy my pieces for a while, and this one is a definite win
