Everyone, I have lowered my overall grade for the Vape Exhale Cloud to a "B" I have had problems with the units dying on me The first one I sent back and was sent a replacement Now the replacement is dying on me! I hardly use the cloud, so it bothers me that 2 different brand new units have went out on me Meanwhile, I use my LSV like there's no tomorrow and still have the first V-Tower I ever bought So, speaking of longevity, the Vape Exhale Cloud gets an "F"! They will have to work hard to earn my business again in the future I had "high" hopes for this one and it is a shame But the truth nonetheless Peace and Pot, Tweety
