Just received two 40's last week, and they are amazing so far. 140 for both plus shipping. Only mistake was to not order the variable controller as two of them are way too much water movement for my 160 gallon. I've since ordered, should be getting them in 1 week. As far as noise, they are way quieter than the vortech 25's when they were cranked. Highly recommend this product.
I might add that the light sensor that is supposed to reduce the speed when light is turned down doesn't really work for me. If completely dark the powerheads run at full speed.
