I have used probably 80 rolls or so thus far. It is actually the most consistent I have used lately. I do use it about 5 degrees hotter than the robo filament I used to use. I think hatchbox is pretty good. Esun is great but I get crappy rolls once and a while so I stopped buying it, and there actual spool size is a bit funky. Aspekt (or however it is spelled) is another cheap favorite, but getting harder to find, they have a pattern on the side of there spools. This seems to be re-branded all the time so just look for the patterned spools.
