Got my switchback in the mail today from vaporbeast. Not a bad unit at all. Seems to be well build and solid. Has a good feel to it. It does fairly well at 3.7 with LR cartos. Personally, I prefer higher voltages, so I'll probably stick with my madvapes VV box for my daily driver, but the switchback is a great addition as a backup. Especially since I gave my ego to a co worker to try out. 
For people that vape at 3.7 all the time, I think it would be a great device. Has possibilities for several different configurations, from full size to stealth, multiple cartos, atty and on board juice storage for a small bottle, etc. And the folks at vaporbeast have been very nice. In the intetest of full disclosure, I won the switchback for free when I placed a carto order. But I would have given the same review had I purchased it. Thanks vaporbeast!
