Query: Great but a bit bulky

Having been spoiled on bottled water, the change was a little difficult. However, after hearing all of the negs about bottles and the environment, we decided to try this thing out. The good news is, it does what it says and so far we've had no problems. The installation was extremely easy and the green light is a nice touch. The only problem that I have with it is how bulky it is. Depending on the size and shape of your sink, it can get in the way of doing dishes and what not. However, overall, we are very satisfied with the product.
