It's a cool looking piece, but the glass piece which comes with it has a poor design. It vapes both concentrates and flower; however, the concentrate collects heavily in the percolators. It seems the filtration process is doing a lot more harm than good. Having to travel so far from the initial burn to the user, a lot of the vape (and I'm talking high quality, gold, rosin concentrate) is getting stuck in the percs with no way of retrieving it or using it to your advantage, which means wasted money. I'd stick with a good vape pen or an old-fashioned nail. It's not worth it to me to spend $400 and have so much concentrate wasted in the percs.
Super well made device. The upgraded quartz cup take this thing to another level. Definitely well made. Function on the glass is excellent but the peel holes get dirty very quickly so they may have rough edges. Between the two, I prefer the peak for its convenience but the Switch for the glass function.
