It's nice works great

Grav makes another awesome piece!

At first as with most items for me; the new (amazing factor) set in and I would’ve raced on for days about how great this product is or thought it was. Several weeks in and you guessed it. It’s still Amazing for the price. The only reason for 4 stars is the designer could have put forth a little more work on the “hmmm, how to hold this thing?”.

I’m impressed by the Grav Circuit. Despite its small size (and it is truly petite), it provides a well filtered rip due to the whirlpool effect this rig relies on for percolation. No percs here, your pull dragging your Smoke/vapor thru the rig, water bouncing off the sides of the bottom chamber provide the smoke/water mixing necessary in any successful piece. The base is sturdy, the design exquisite and the product of good thinking, and the cost is fair. I combined this with a Grav male to female converter and a 90 degree reclaimer joint by Grav as well. It looks a little Frankenstein like with these attachments, but it’s super effective. For a total of about $100, you can make a really dope reclaim dab rig, by a good company in Grav. Can’t beat that at all. Highly recommended!
