Let me start by saying this pump is a BEAST. The 5700 GPH flow rate creates an impressive waterfall (mine shoots water 8' high like the reviewer mentioned). The stainless steel construction feels premium, and after 3 months of continuous use in my koi pond, zero corrosion.

PROS:

- Power delivery is insane - moves water like a champ even through my 2" piping system

- That 32' cord is a lifesaver for awkward pond placements (no extension cords needed!)

- Surprisingly quiet for its size - just a steady hum that blends with nature sounds

CONS:

- The oil situation is weird. Like another user mentioned, finding maintenance oil is nearly impossible unless you want a 55-gallon drum

- At 5.5 amps, this will noticeably impact your electric bill if running 24/7

- Had one scare when leaves clogged the intake - took me 20 minutes to disassemble and clean

Real talk: This isn't a cheap pump, but after seeing multiple users report 5+ years of service (and one unhappy customer with an 11-month failure), I'm cautiously optimistic. Just installed mine this season - time will tell if it lives up to the legacy!
