I specifically ordered the Scope to use with my Arizer Solo 2, and I'm quite impressed with it's performance. The glass seems thick enough, and sturdy enough, but that's no reason to be careless. The draws are so much easier with the Scope compared to the Solo 2 glass stems. Shipping was incredibly fast. Don't forget you a 14mm adapter which is also available here at PUFFITUP.
The draw is smooth, the glass is tough, the added moisture reduces dryness of the vapor very well.
I've gone through about half a dozen of these and on half of them water got in your mouth, but all of them broke easily which is why I kept buying more. I'm going to invest in a thicker bubbler, because a tiny drop is all it takes for the bottom to break on the inside. The glass is thick everywhere other than that joint
Nice heavy glass, seems very sturdy, and dissipates heat well.
Cools down vapor for sure, nice quality, feels durable
