I've only been using them for a couple of months, but so far, so good. I dose out of a pair of 1G jugs and they are used up at the same rate.<a href=showthread.php?s=&postid=15578605#post15578605 target=_blank>Originally posted</a> by Mandarinman13
Do the drews dosing pumps work well for everyone thats using them??
Is one pump fairly accurate compared to another so I wouldnt have to be trying to tweak the two different timers to match dosing amounts??
And are they reliable?? I know they have a 1 year warranty, but has anyone run them for 2-3 years with no problems?
Thanks for everyones help!
