Im running about 20 won bro's (good price in a group order last year)...from 50w glass to 500w titaniums and everything in between
the 500w titan (non lcd) crapped out in a month, is either permanently on or permanently off. now just whack the controller from the left for on and from the right for off
works fine for keeping a 300g barrel at temp
50w's (all 4) cant get a 10g over 78'F
350w titans and 300w glass have been great, although some of the 300's (4 outta 6) need to be set anywhere from 79 to 89 on the dial to hold 86'F in the tank. however once they're set they dont drift. running 4 350w titans and no complaints on those
no complaints on the 100w and 150w glass heaters either
