Looks like you have a monster mod. It would probably tip over my little 1-cell mods...
I know this is an older thread, but it influenced my decision to buy the Longmata Motar and I wanted to add my 2 cents for the next guy scouring the net researching this device. The's not much out there.
I paired the Motar with a big 4 battery brick I had kicking around and I am digging it. I have the RX300 at 24W which is working out nicely. A BB-ish sized dab gets me 3 or 4 milky hits. I've only had it for 2 days at this point, but so far I am pleased with it, especially for the $22 USD it cost me. It's nice to be able to do a quick dab without dragging out the rig and the torch.
I just love this Motar quartz bucket. It just seems to fluctuate too much with inconsistent dabs ... some are tasty and awe inspiringly beautiful lol and most are meh with a small puddle of cooked oil leftover.. theres gotta be settings that dial it in most everytime!
