I like this bong a lot. It has 3 methods of cooling the smoke: standard bong effect (running smoke through the small resevoir of water,) then a percolator and then a recycler which takes some of the smoke back to the first filter, then the perc then possibly recycled again. So it cools the smoke (in my case vapor) excellently. What I also like is it's got a little bit of volume which improves the smoking experience for some reason I'm not quite sure of, it's not huge though about medium sized. As stated I use this for dry herb vaping with my dynavap and S&B Plenty. It works especially well with the dynavap seen as the plenty comes with a pretty effective cooling solution any way. But I would say it improves the experience of using vaporisers significantly. I've knocked it oved a few times (while it was already on the floor) and it has been completely fine- even once where it hit my metal chair leg which made my heart flutter a bit! I will have to be more careful... Overall I like this bong a lot, it's fairly priced and it does everything I could want. If I was to make some small critiques I'd say it would be nice if it was slightly larger and I wish the top part of the percolator wasn't coloured green, I think it makes it look a bit cheaper personally- just all plain glass would be nicer... also the percolator is slanted which is slightly annoying to look at. However these are small problems and I am otherwise very happy with it.
