I ordered the Piranha Quartz One Piece Beaker Rig w/ Thick Bottom Reactor Core ****** back in January of 2019. Used it for about a month before I broke it when it tipped over onto granite. Bought this one as a replacement in March 2019. It arrived in perfect condition. Love the terp vac ****** and how well it hits. Used it for a couple of weeks before it started to gunk up inside. Put in 91% isopropyl and a little bit of salt with the piece in a plastic baggie. Sat in the alcohol for about a couple of hours. I went to go shake it around to get anything that might be stuck and the downstem inside broke off. I was super ticked, but I figured it might still hit alright if I could get the downstem out. When I was shaking it to get the downstem out the ****** detached from the front. This piece fell apart on both sides of the most important seam. I ended up ordering a silicone rig just in case it is me, but I have never broken a piece of glass and went through 2 quartz rigs in a couple months. I cannot recommend this rig to any but the most delicate users, but give it two stars because when its in one piece it is my favorite.
