We bought this for our office and it works great! You can definitely hear it filling with water and the ice emptying, but it's not so loud that you can't hear anything else. The ice doesn't stay frozen for ever, but it recirculates it, so the fresh ice is on top and the stuff on the bottom will melt back into the reservoir. There are 3 of us that use it on a daily basis in the office and it keeps up with our demand. I highly recommend it!
