So to preface I have received 2 of these bangers. The first one had a defect and airflow was not great with any pearl or rig. Reached out to them on Instagram and they had a replacement out in a night.
The Kamasutra 3.0 with a 20mm se 2.0 or the 30mm se3.0 is possibly the best setup I've ever used. This stuff slaps 300+ dollar setups I've hit out of the water. The heat retention is unreal I can't recommend this setup more. It handles small to massive dabs with no issue. Flavor is superb. The neck work and placement makes q-tipping a breeze.
I'm going to be a vocal advocate for this brand as long as their quality and customer service stays this superb!

love the way it vortexs so perfect. great for fat globs of rosin:) from: iDab4Daze

Stays hot for MINUTES this thing is crazy

Great for huge dabs, stays hot throughout the whole thing so you get every bit of vapor out of it! Pair with SE pillar for the perfect dab. I used to use campfire quartz and I’d say for similar prices, I am going to use Om from now on!
