Cracked head near wire By Marie on 7/1/2017Marie wouldn't recommend this product to a friendJust the same got a shock this morning and noticed 3 of my pumps are cracked one is 6 months old and the 2 other near 2 years, this is very strange and it also runs backwards
2 cracked in the same spot, electrifying my tank By Danny on 5/11/2017Danny wouldn't recommend this product to a friendI had 2 of these in my tank for just barely over two years. They both cracked in the exact same spot--where the label is on top right where the power cord comes into the devices. I noticed this when I got a nice shock sticking my arm in the tank. This is without a doubt a faulty design if both cracked exactly the same way. I'd expect to get more than 2 years out of a $50 power head that I cleaned every 3-4 months. I will never buy these dangerous poorly designed things again.
Quiet consistant quality time and again. By Goldwing Coral on 11/26/2016Goldwing Coral would recommend this product to a friendI've used many of these pumps over the past 10 years and while I've owed others none have worked as long. Great balance of function/cost.
