REVIEW –
1) Amazing. Replacing 13 year old exact same machine. - Great pump. It's literally silent. The vertical float keeps the water level low. I just replaced a 13 year old machine that didn't burn out, just simply needed a new switch. I've fixed that unit and it's working, I just bought this one to use and keep the old one as backup. Get it, you'll love it.

2) sleeping easier - With all the heavy rain in the midwest this spring, our old pump was going off every minute or so. I investigated to see how much water was coming in. There was a lot, but the real problem was that 1/2 the water being pumped out was backflowing into the sump after each cycle. Did some research and learned about check valves, which we apparently did not have, and realized that our 10 yr. old pump was basically 20 yrs. old since it had been doing double duty. After lots more research, we decided on the Liberty 257. The reviews are excellent and there were no mentions of the switch problems that seem to plague the Zoellers. Not to mention the price and warranty are better. It's been installed for about a week now (hardest part of that was cleaning out the sump basin) and is running well. The old pump, while extremely dependable, was also extremely loud, as was the noise of the water rushing back into the pump without a check valve. Being as how the pump was right under our bedroom, I was losing a lot of sleep, both from noise and worry. Now I can barely hear it (and just worry about not being able to tell if it's running or not.) Much less water comes out the discharge and it seems to run a very short amount of time. That being said, it seems to be keeping up OK.
Update: We think we figured out the issue. The float differential (the difference in inches between the "on" level and "off" level) is only 3.5" on this pump. Most pumps seem to have a greater differential than that (and thus pump out more water at a time.) This pump is working great with heavy use, but consider this before you buy.Update #2: Came back and updated my rating to 5 stars. We just had a torrential overnight rain the likes of which I've never seen and the pump was awesome! The water was pouring in so fast, the water would come within a few inches of the top of the basin before the pump could cycle on, but when it did, it emptied it completely. Wow! It's like it rises to the occasion of abusive conditions! :) Thank you, Liberty!
