well. The mod is not that expensive, so you get what you pay for. I too have seen you tube videos on people using LR attys, and regular 510 attys as well. The juicing operation isnt as effective because it doesn't have a ceramic cartridge, or cotton like a cartomizer has, so you'll be pumping a lot more just like you are dripping a lot more. I think if you use it correctly, which is...use an LR Cartomizer, fill the cartomizer yourself...and when the cartomizer is almost close to drained, pump your wet box until the LR 510 Cartomizer has juice again. A lot of people are putting empty cartomizers and expecting it to last all day, but that's not how it works. You need to fill the carto first, then refill or "re-feed" as needed. I'm going to try an LR atty when i get mine, and physically drip on it to get it going, then I'll see how the feeder works while I watch the juice come up from the bottom. After 4-5 vapes, you'll have to squeeze again, but it still is a lot better than carrying around an extra battery, extra juice, etc.
I read that also, where you can place a small 1x1 piece of silicon or paper towel to soak up the dripping. I'm also going to put some flexible protective adhesive around the switch when i get mine. That will allow the tactile switch to work, while also protecting it from getting juices near it and around the wires. You could go all out and put silicon around all the wiring so no juice can damage any circuit, but that's overboard for a 45 dollar device. Hey if it works for 5 months, then i got my money's worth.
I'm still going to try it with an LR atty first, but I'd much prefer the LR carto so I can fill it with 1.5 mL, and then refill when necessary. Also, I love the idea of using an LR 510 on it, because since we all have to re-drip about every 3-4 vapes since the LR goes through so much liquid, pumping it will be very easy and effective. no more dripping and driving, no more missing the drip tip when drunk

NO more carrying around a bottle and dripping every 3 vapes...the idea seems very very good...now it's all about the build of the device.
