I had ordered the Stealth Ascent Vaporizer about 2 in a half weeks ago. This is my 2nd portable vaporizer, first being MFLB. I did enjoy the discreet design, fast heat up, good vapor but felt like it took awhile to finish one load, I always run it on 430, wish it could get hotter for quicker sessions to serve it's stealthy purpose IMO (My opinion may be influenced by MFLB). But my unit completely stopped heating up after 2 weeks of straight use. When I turn it on it stays on 70, but when I plug in the charger it starts heating up right away. When plugged to the charger the ascent doesn't show its being charged either. I am very disappointed in the reliability of this device, for I really needed it at the time it stopped working. I have only dropped it once from waist height, no biggy. One week after for no reason just stopped heating. I spoke with their customer service, and they will give me a refund after they test it. I sent my Ascent yesterday, after cleaning it out as best I could with ISO and rubbing some Rosemary oil around the package (in case it still smelled). Overall I think the ascent is a good design, just needs to be tested more for defects, and if your getting it for stealth, I don't think its the best except for the fact it looks like a cell phone/mp3. I am going back to MFLB, their sending me a new LB and PA. Hope all will go well and I get my refund. Will keep you guys updated
