Before I start I feel that a little background information is mentioned prior to my feelings toward the MFLB -I researched vapes, "travel" vapes, and overall vape experiences and products for about a month in addition to vaping multiple times prior. anyways, I used my MFLB for probably about a month before it went to its current resting place, my dresser drawer for about the last 10 months. The initial novelty and "new piece/smoking/vaping device" feeling lasted probably about as long as I used it, a month, before going back to my gandalf pipe. I just never really felt like I was getting the most out of the different buds I tried in my mflb, (please remember I did a ton of research so I had my bud grinded up the right way and all of that jazz) The buds would looked like they had been baked in a small oven and a light vapey popcorn smell could be smelled from a few feet away. I ended up going back to my MFLB after about 6 months of non-use. I charged two batteries in the charger, and the mflb worked for about one drag before the battery seemed drained. Now I am not sure if this is a battery/charger/MFLB problem, but I have never had a good enough experience with the product thus far to care.
