  4. Super quiet, powerful unit. 4 Star Review

    Posted by on 13th Dec 2015

    I have had it for 2 1/2 yrs it is great. recently it seems to have lost power. I probably will get another if its the unit and not clogged air stones. It really is worth it.

  5. Nice quiet unit 4 Star Review

    Posted by on 13th Jan 2012

    I have been using this 24/7 for about 4 months. It is a nice quiet unit. I like that the valves can be operated individually. The unit builds up almost no heat.

    I did not give it five stars because the L shaped rubber pieces with eventually get brittle and fail. The description say 16 stones...??...
    That is a pretty ambitios estimate. I power four 5 gallon pots and the water is at a constant "boil". I would not go 16 pots. More like 8 comfortably.
