Agreed Tunze are so nice still a little pricey. I would buy Tunze before Vortech. You cant beat German engineering. That might be why Jebao completely ripped off the Tunze power head. You are right about early Jebao power supplies. They were ordered in bulk and were sold with bad power or under powered power supplies. Jebaos customer service sucks. The early WP's were under rated for the pump and or power supply went bad prematurely. Or they were sold for a power supply for another country. What I have seen from Jebao in the last year is so much better than what they offered in the past. I love my Tunze skimmer. Tunze makes superior product. But as cheap as Jebao is I lean towards Jebao. My first gen WP25 is still going strong. My first power supply went bad but the pump is still working with a new dual controller and updated power supply. I cant complain.
