I was price comparing with Aldi, where I normally do my weekly shopping and you were matching their prices on everything. The fact that I was able to get my groceries delivered for basically the same price was very helpful, as my family had the flu and I wasn't up to shopping in store.

Easy Fix.

Very easy to replace the unit. Adjusting to fix perfectly and set tank water level is very easy to accomplish. Makes you look like a master plumber. Great instructions.
