It’s a shame, because I really like this squonk mod. It leaks like crazy. I’ve seen some other post around, and it’s definitely true. Here is the deal. Whatever they used for a seal just doesn’t hold up. It’s a gasket made of a cardboard like material that only slows down the liquid from entering your mod, but certainly doesn’t stop it. The 510 pin is also not spring loaded, and the connection gets damaged because of it. I bought 2 of these. Initially, I thought I messed up the 510 and all would be well if I used a spacer under my rda. Nope, the leaking once again appeared on the second mod. I actually used silicone and made one hell of a seal where the 510 meets the mod. I did this on both of the ones I own. I actually thought I got it with one, but about 4 days later, there was the leaking again. It slowed it down, but it did not fix it. If anyone has had success in fixing this issue, I’d love to hear how. It’s really a shame. The box looks great and it does perform well. Everything about it works pretty well until it goes to leaking. hcigar really blew it with a box that could have been a solid choice. I liked it enough to purchase 2, but I’d not recommend anyone grabbing one of these. Too bad.
