Ok, First things first, I have heard bad reviews for Grace Glass quite a bit. The things I like to ask people giving the reviews are, where did you buy it? How much did you pay? Too many people are buying counterfeit pieces from these chinese/asian run and supplied websites and think they are getting the real thing. 85% of the time these sites are selling counterfeit or defective manufacturer rejected pieces. If you think you are going to get a $200-400 piece for $50-75, you are not only gullible, you're stupid. That being said, If anyone asked me what I think of my Grace Glass piece, I would tell them that the box says it best,"Finest Quality Bongs". I have a 22" straight cylinder 2x12 arm tree perc, with 6 arm diffused downstem from Grace. I also have a Grace Glass ashcatcher/precooler with a shower head diffuser to honeycomb perc. Iwas absolutely amazed at the quality vs. price($145) of this piece. This thing is thick(7mm), heavy and very beautiful. The percolators make your hits super smooth for such a large piece. I would recommend Grace Glass anyone looking for a nice piece between $100-200.
That seems like way to much diffusion and would be really draggy. 145 for that whole setup seems way to cheap esp for 7mm glass.
I have 2 GG pieces and i would have to say the same sir. On is a beaker the other is block perc to circ with a saxxo neck. Love em, they are both used daily
