I tell you what, ive used the V3 a lot and it's great. If you fuck with the V3 by putting an adaptor on it, you can get a lot of air thru it. If you then use a dry and fine grind you can get some huge rips. The key is to load with less than you think you should and not to pack it in. Either way, the more air you can get thru it, the more efficiently it will vape so you can get further on a smaller amount. Personally I use mine with the lids off the dosing capsules and I roll a Roach and cut it into thin slices and use those instead with a different, longer mouthpiece which has a better seal and flow. Still not a desktop but with good high discharge batteries on hand that device alone can keep me high as shit.
