it works great. of course the vape all comes down to how well you build the RDA. I suspect anyone who likes dripping would like the convenience of the VapeMate. I bought a "blem" so it was a bit cheaper, and I don't see anything wrong with it. The down side is it looks weird and probably pockets weird and feels a bit awkward. it just feels juice down into the top of whatever you're using, so doesn't work much differently than whatever it's on (other than perhaps a very slightly cooler vape due to the added distance from the atty it's on). I got this in the mean time of trying to decide if I want to get into a bottom feeder, like the Reo or whatever.
