I have an Insinkerator. I use the hot several times a day and have been for a year so I think the novelty has been replaced by habit. I have chilled water in my fridge and my tap doesn't taste bad enough to bother with the filtered cold (I was I mean am planning on replacing my fridge with one that doesn't have a dispenser so thought I'd want the filtered cold).

So far, no problems except for my GC installing it wrong and burning up the tank on the first fill. ISE service was excellent and they replaced the tank quickly.

I have a "quick and hot" brand hot/cold unit and some other brand faucet and I LOVE, LOVE, LOVE it! It's plenty hot (and I don't have it turned-up all of the way) and the filtered water is really nice too. I use it almost every day (usually several times a day). I also like how the MP brand or Q&H has nicer looking faucets in various finishes. It is one thing I'll never go without in my kitchen!

Good point about the faucets. Even the same brand can have a range. ISE has faucets that range from the 80s type (look like they belong in an airplane) to much nicer more expensive ones. I actually picked ISE because they had a faucet that looked OK with my main faucet, but I think mixing brands is a small thing.

We are going with the Vertex bottleless water dispenser.
Our freezer has an icemaker, but we could not get a fridge only unit that dispensed water. This will encourage more water drinking and ice tea making.
