Pros
- Moves about 130 gpm at 10 ft, near the top of the 1/2 HP class, for under $300
- Cast iron motor housing sheds heat for a long service life
- Piggyback float plug lets you run it by hand to test or clear the basin
- Sold by Amazon with a three year maker warranty
Cons
- Flow collapses past 15 ft and stops before 20 ft, so it suits short lifts only
- Short 8 ft cord may need the outlet close to the basin
- Needs a basin at least 18 in across for the tethered float
