I purchased this unit in September 2010, I installed it myself in my first floor utility room. I live in Alaska, I'm on a well which means the incoming water temperature drops in the 30's during winter months. I have only had one issue to date, which was just a rubber seal which was covered under warranty by manufacture. Quick and simplement replacement with free shipping over the phone. Other than that issue the only maintenance I perform is draining and cleaning of filters and dust in and around unit. Couldn't be happier, unlimited hot water in Alaska!

Bought this for my mom. She is a voracious Penguins fan in Sabre country so she has a hard time getting news on her team. She is thrilled to have this DVD and has watched it repeatedly.

After installing I had more problems and had to take it into the computer store to be cleaned and had it removed.

I am extremely happy with this pair. I wear a size 12, and these were initially too snug for my feet.

Of course, it's impossible to cover every possible market in one book. Several publications I'm interested in are not included, BUT they also offer an online update service which I have not had time to check out yet. Their tips on marketing are good.
