had a 2100 and a 2500, they are an economy pump in my opinion, they both lasted about a year, at 7-8 months they both exhibited "fail to restart" when the power goes off then back on, you have to unscrew the cover, flip the impeller with your finger, get sprayed with water, put cap back on, works till next power out.
They did seem to get pretty warm also. To be honest, I never felt safe sticking my hand in the sump and felt a sense of relief at not being electracuted each time.
