I've had my Focusvape Pro for almost 2 years now and it still works like the day I bought it. The first thing I did was trash the "filter pod" and screen. I replaced them with two, .375" screens, one in the top cover below the tip, and one I place on top of the weed in the bowl. Much less draw resistance and I have to clean the screens less often. I get great rips at 380F, and 10-12 hits per bowl.
The Pro has outlasted ALL other vapes I've owned, and I've tried most of the so called best. My pro is almost 2 years old, no other vape has lasted this long. I use the LG batteries in mine, forgot the model# but its the brown one, i get a couple more sessions than with the sony. I'd like to see focus make a box type vape, similar to the Boundless!
