I haven’t tried the Samsung 30Q or the Fogstar cells.
I definitely prefer the LG HG2’s to the Sony VTC5’s or the Samsung 25R’s. They seem to run much longer and much cooler then the Sony’s and they pack more punch than the Samsung’s.
At the moment I have plenty of battery’s. I have a friend who ownes a really good head shop in my area and i get my LGHG2s for £4 each when I buy a few at a time lol can’t go wrong at that price.
Bud, for the tubo I recommend you use a different mouth piece with a longer vapor path. I know you do not like to hit the grasshopper on its own and the tubo is the same IMO. Vapor is hotter and the mouth piece towards the tip gets hot. Cheers.
DDave mod all the way!. Check out this site! The smaller path of his stems cools the vapor better than stock Tubo/Milana mouthpieces. The V3 cooling Tube, though, is the best! https://www.ddavemods.com
