This review is for 3-in-1 Water Cooler with Ice Maker, Hot & Cold Top Loading, Water Dispenser for 5 Gallon Bottle, 33LBS/24H Ice Maker with Child Safety Lock, White. I ordered this cooler because 1) although I have a very nice ice maker in my full-size refrigerator, it's noisy and awkward to get ice from, and 2) I am interested in obtaining very quick hot water. (more about that later) This is my first of this type of water cooler/heater, so I wasn't aware of any issues to do with a five-gallon water bottle (other than I knew it would be heavy). My first thought is to tell you: the instructions say to use a "pierce-able" water bottle, but hubs and I didn't think that was terribly important. All you have to do is flip the jug over and get the neck in the hole quickly enough. Trust me: It's important. After I cleaned up the water that splashed all over the floor (a 40-pound bottle of water is hard to control even with a very strong husband in charge), my next step was to order some pierce-able/reusable bottle lids! Once this first 5 gallons is used, the pierce-able lids will go on, never to be left off again. Not to be deterred, I am using distilled water for my hot/cold water and ice supply, but that's only because I distill my own water at home, and the supply is essentially free. Last night when I tasted the ice and the water, I would say, though, that it's a bit flat tasting, a typical characteristic of distilled water. The advantage, of course, of using distilled water only is that the machine does not have to be de-scaled, and I live in the Arizona desert, where the water is so hard you could use it as a substitute nail. It's unreal how hard our water is. If you don't want to use distilled water for whatever reason, be sure to keep your instructions for how to descale the unit, as you will need to do that with fair frequency, or risk destroying your expensive machine. Now, to the function. Child lock: This is a nice safety device that really doesn't work all that well. The first thing I did after setting up the unit, and while admiring its sleek appearance, was to swipe over the top to remove a speck of "dust." Next thing I know, the child lock is OFF and water is going everywhere! I accidentally unlocked it myself. Now, we don't have children at home, so this is not going to be an issue for us, but if you have children, you might want to consider that the Child Lock is trivial to disengage and you can have water running everywhere without expecting it. If it's cold water, no big deal (relatively speaking), but if it's hot water, your child can suffer burns. THIS is the reason for my downgrading one star. (Additional note: I do think that once the button is un-pressed, the hot water flow stops. That's just not quick enough for me.) Cold water: Once the machine has a chance to cool down, cold water is easy and a no-brainer. It doesn't flow particularly fast, but you might not even notice that. At least it's chilled very nicely. Hot water: This was a bit of a disappointment, but only partially. There was no indication in the product description as to how quickly hot water can be dispensed. So, I was going on "hope," as I really wanted "instant" hot water. Unfortunately, it takes about 10-15 minutes after the "Hot" button is pressed to have fully hot water. But the GOOD thing is that until you turn off the "Hot Water" function, you continue to have "instant" hot water. I haven't yet tried to see how much reservoir of hot water is kept, but it stands to reason it will be a few cups at most. Ice Maker: the ad says 7 minutes, and I was left wondering why 20 minutes went by and I had no ice. Well, it was because I neglected to turn on the "Make Ice" function. Once I remedied that, sure enough, ice started coming out in about 7 minutes. The ice at first is just barely frozen enough to stay solid. After continuing to fill the ice compartment and sitting for a couple of hours, the ice is definitely much firmer. I was able to use it in my morning protein shake to chill it down and blend for a nice thick shake. Noise: there is very little. An occasional whir or glug. You can sometimes hear the ice drop, though it was in the next room to my bedroom and I didn't hear it all night. There's a silicone pad to help with ice-dropping noises, but it's only effective for that first few drops. After that, the ice drops on itself. Considering all the little noises that exist in our modern world...this is minimal. Other considerations: The machine is small, and unless you are a Lilliputian, you might find yourself practically on hands and knees scooping ice into your cup. You might also drop the ice on the floor, even if you use the little scoop (which is nice to have, by the way), so an absorbent, non-slip mat would be a good idea to place in front of your machine. Other than that, I actually love it! I do hope you will pay attention, though, and get a pierce-able water bottle and save yoursel
