Being a "low-tech" kinda guy, the TWO vapes I own are both compact, portable, and cover all my needs. The VaporGenie is a great all-around pipe that evenly vapes the load (once you get the hang of it). Its only downside is you need a butane flame to heat it, so I use it exclusively indoors. My Launch Box is the MOST compact and stealthy vape I have seen. Its other advantage is that it can be used outdoors, and without a lighter. There's still a little bit of breathing technique to avoid combustion with the LB, but it is a very effective and stealthy vape. Both units have a minimum of moving parts, which IMO also minimizes the chances of breakdowns or breakage.
