For this price it's a very nice pump. I had Tunze pumps and the WP-40 is a little better because it makes waves. No more noise than the other ones. Very good flow and water circulation. I had a little problem with the AC/DC adapter and they send asap a new one, free. The response on the sended mails is very quick and friendly. This is a very good company. I will buy again.
Thanks

This is a great product :). Extremely good flow rate. Very good price. :)

Great returen for the price payed, eccelent pump, a little noisy but other than that and the faulty light sensor it preformes perfectly, defenetly great price for a great pump. Now the only thing left is to see if it pass the test of time...

Nice water flow, noise comparable or even lower than produced by similar, but more expensive pumps. So far, the only disadvantage is, when it's used in longer tanks (2.3 m). The controller has too short pulse intervals to generate sufficient waves. I would buy another one, if this could be fixed.

Superb product for the money really works well, have bought 2 f or an upcoming upgrade but am using 1 in my current 4 foot tank. It has replaced 5 powerheads and still gives a better flow, can't fault it!

I bought this pump for my 50 gallon tank and i can't believe how good it is, the waves are totally controllable and it is so quiet you don't even know it's switched on. In my opinion this is even better and more contollable than the mp40 and at this price you can't go wrong. As an added bonus Fish-street.com got this deliverd to the UK in only six days which is excellent.

best wave maker for cheap price. excellent !!!

The pump is fairly quiet (it takes a few days to break in) and works as described. It pushes ALOT of water. The only problem is there is no control over the top flow rate. This can be fixed with the variable power supply.

Excellent pump.

great service and pump
