I can't believe I am still using the first omi cart I ever got/filled (2.4) I know I am not a heavy oil hitter, vape mostly, but I believe I got this around the end of Jan. I rotate around between devices/carts. I have noticed my first bit of leaking with this cart. Nothing major, just a bit of oil oozing from the threaded end. A little iso wipe took care of it, and it doesn't seem to be leaking now. I do have to do the clog "pop" at the beginning after a bit of warm up to get air flow, but this has been the case pretty much since I filled it.
Looks like the V2.5 top should be here tomorrow. I will go ahead and package up the HVD top once it arrives, get it ready for shipping back when we get the word.
