I have had 3 of them in 2 tanks, and they work great. i have had them leak voltage in the tank, but it doesn't seem to hurt anything. 1 i bought new and is now a year and a half old. it is not leaking current and works. 2 k4 I bought used and they leak a small amount of current. If you are comparing them to tunze anything you are living on a different planet. K4's new are about 50-60 bucks, and you won't find an off the shelf powerhead that will move water like that w/o mod's, and for that price. Tunze powerheads that move that kind of water(1200gph) will cost you about 4 times the price. I personally would rather buy a brand new k4 ever year for 4 years. It gives me another reason to go to the fish store!
Best econo powerhead out there!!! I know I am cheeeeeaaaaap! hahaha!
