This is my first large bong. Wasn't accustomed to all the percs and diffuser etc. A little worried about cleaning at first. This thing is great. Hits very nicely. I clean after every use and it's simple. Just put cleaner in it. Let it sit a couple minutes and rinse. I wouldn't let this thing get gummed up. Seems like it would be hard to get clean if you did. Worth the 127.00 I paid for it during 420.
