I bought this cartridge after hearing my budtender rave about it. At first I was quite happy with it. The cartridge hit hard, pulled very well and tasted great. While carrying it in my pocket, it unfortunately separated. It was about 3/5ths full. Leaked errywhere. The construction wasn't as it seamed. I definitely appreciated the dual coil set up as it provided long cool hits. However, I didn't appreciate how the bottom chamber (which houses the coils) and base are essentially pressure fit. Also, i didn't like how the clear cylinder was actually plastic. I feel that may have altered the flavor. Other high end cartridges I've used are compression fit. I don't think I'll get one again. Good while it lasted though.
