FYI for anyone who's considering an EVO, they're Amazing little pieces of kit. They use little to no electricity and they're tiny!!!

Here's the breakdown of the 3 Evo models:

Flow Rate: 750 gph Power absorbed: 4.5 Watts
Dimensions (Legth x Diameter): 3 1/2 in x 2 3/4 in
Outlet Size (Diameter): 1 3/4 in

Flow Rate: 1050 gph
Power absorbed: 5 Watts
Dimensions (Legth x Diameter): 3 1/2 in x 2 3/4 in
Outlet Size (Diameter): 1 3/4 in

Flow Rate: 1400 gph
Power absorbed: 6 Watts
Dimensions (Legth x Diameter): 3 1/2 in x 2 3/4 in
Outlet Size (Diameter): 1 3/4 in

As you can see, they have little to no power use, which means little to no heat... They work awesomely on wave makers from what I understand, and with the new redesigned internals, they have a longer estimated lifespan ;) My 2x 750's get in on Monday!
