Shakey,
Like any other peice of brew gear you have, it is easy to clean, if you clean it after each use. If you do not clean it after you use it, then it will be very hard to clean later.
It is as easy to use as an immersion chiller and works about 10x as fast. I can cool 7usg wort from 212F to 65F in about 5 minutes with tap water about 55F. Also, I siphon, no pump.
Hot break stays in the boiler, but all of the cold break goes into the fermentor. This isn't really a problem, as the yeast need it anyway.
