So I've been looking into dosers for a friend, and I'm seeing a surprising amount of mixed reviews. - I see tons of threads praising the eKoral, then met someone who had theirs dump the other day. - Kamoer are lab/medical grade, but their stuff for aquariums has been less than stellar. - Kore 5th is okay, but I see lots of people complain about dumping and failure. - Neptune DOS is a timebomb, it WILL dump for sure on you. I don't trust neptune with that stuff. - New Bubble Magus dosers have their timers die in about a year (check reviews everywhere, seems 1/3 reviews are about the doser turning into a paperweight). So whats the deal here? What would you guys suggest? None of them seem to stand out in a very positive manner.
