Don't think of it as a tree perc since the bottoms are welded. It's more like a 40 slit gridded upline. I mean, at least that's what the pull feels like
I get what you are saying about the joint support, especially if you leave a hot vape on there. I only use it with an e-nano, lotus, and solo so it doesn't get too hot. And if I use an e-nail I use a dropdown so it doesn't get hot at all.
However, this joint (even without the support), feels stronger than a lot of the female pieces with joint supports!
If anything, get it to use with everything else besides your LSV and sub (I know you got other vapes and don't you dab? haha).
Or just rig up your own joint support like so
Top quality Walmart product right there! The joint ain't goin' nowhere ha!
