Because of all of the great setups available it almost seems a step back to take an interest in carto's, but I wanted to give them a try. I ordered some lr xxl's from MBV along with some juice I ordered for someone as a Christmas present. I watched a few videos on the setup, and I used the condom method to fill it with juice. The filler material appeared fully saturated so I gave it a few vapes. The first 3 or 4 vapes were wonderful with tons of flavor and vapor. But then, after only a few vapes I start getting a burnt taste. I have read that once filled they should last a typical vaper a few hours, so does anyone know what I may be doing wrong? It has great flavor, and if I can get it working properly and it works as well as it did on those first few toots, I will be getting a carto tank and adding cartos to my vape arsenal. Is anyone familiar with the boge xxl cartos and the issue I am having? Should I be hitting it the same as a clearo, or is the actual draw technique part of dialing in on these things?
