So far, so good! I've ran numerous tanks through so far and haven't had an issue (that I didn't cause!). There'll be another one of these in my near future. I PM'ed Angel about an aftermarket Pyrex tank section, but haven't heard back on the subject as of yet. I tend to use a lot of juices that crack, haze, or downright melt polycarbonate. I realize the as section can always be used in these cases, but I am going through tanks so fast, I really want to keep an eye on the level. If you wick with cotton, it only takes once to learn that lesson!
Hope you enjoy yours!!!
