Grav Labs Helix USA Made

My ex business partner and I spent about a year traveling around the country in search of the best hitting glass. I bought this locally here at smoke and Smitty's. I remember, we walked into the store and asked for the biggest hitting dab rig they had. I think they nailed it with this one. This thing chugs like a bong. I don't know if I have had a dab rig that can give you a bigger hit. Don't really know how to price this as they don't make them anymore from what I can see. It is Grav Labs, but it is also handmade in the USA. It is their elite line.
