I bought 5 of the LR 801 Fusions from Ikenvape because I was having a heck of a time getting good Boges. First one lasted 9 days before I had to replace it. (Slotted by me in a J-Tank from Electronicstix) Went back and bought 10 pre-punched SR 801 Fusions, first one lasted maybe 5 days, second one is on day 8. I will stick with Ikenvape from now on.
If Boge's quality had not gone bad I would stick with them, but I had so many problems with my last order that I decided to go elsewhere. I have only tried Iken's 801s, so I can't comment on why they are better than anyone elses, but they are definitely better than the last batch of Boge's I got. I just wish Ikenvape would pre-punch LR 801s
