Product review (4 stars): A good temporary solution
This ice machine does what it promises, for about a year of daily use if you don't maintain it. It's sturdy, starts making ice in about 15 minutes, and can keep up with constant demand if you keep it topped up and store the ice in a location other than its ice basket (it stops producing ice once a certain level is reached to prevent overflowing, but the provided ice basket holds only enough ice to completely fill about 6 cups if you're lucky).  The 3 ice sizes aren't much different from each other, so which one you'll use will end up just being your personal preference. The small option produces ice a little more quickly, but the provided cubes melt faster and aren't very space-efficient. Larger cubes perform much better but are subject to diminishing returns for their production time.

Peel off and degunk the stickers on the inside of the lid ASAP. The moisture from condensation will have them fray and brown eventually, so nip that grossness in the bud back when it's easiest to peel all the stickers off.

I recommend against operating it in direct sunlight, anywhere with poor airflow, or areas with high temperatures. It will have to work harder, consume more electricity, and produce less-robust ice.

The life of the machine can be extended but that requires a little vigilance and frequent maintenance. For our corner coffee shop, it ran about 10 hours a day, 7 days a week. This is most likely heavier usage than most home situations. Here's what we found:

1. Never turn it on without enough water in the tank. It won't destroy it, but it does add extra wear to the pump. (And the pump ultimately determines its maximum lifetime, see #9.)

2. Make certain to plug it into an outlet with a working ground pin. Any shorts or built up charges will behave unexpectedly and possibly catastrophically if you don't.

3. Use canned air or other computer cleaners to dust the fan grate on the side, and the airflow grate on the back. How often you should do this unfortunately varies wildly depending on placement and your area's dust buildup. This also helps reduce electricity consumption.

4. If you use the machine as frequently as we did, it's a good idea to drain the water at least once a week and let it dry overnight. Prevents mold. If you use it less frequently, attempt to drain it after every session, so it never just sits with water in it.

5. Use distilled water to fill the machine if you can. Keeps the white interior looking nice longer, and prevents mineral buildup.

6. You have to clean the interior. Washing the ice basin out with kitchen cleaner and water is a regular occurrence, but after some months you'll need to unscrew the casing, take off the back shell, and remove the revealed screws under that white rim to get at the rest of the ice-making surfaces. Water buildup, possible mold, collected dust that was washed into crevices, etc.

7. Last and certainly not least, if you are planning to use this for foodservice, or want to make sure that the ice is sanitary, you'll need ice machine-cleaning solution. Regular disinfectants and cleaners are too corrosive for the chilling surfaces. It's easy to find at restaurant supply stores and other specialty outlets, but that means you'll have to find those places first. Most ice machine manuals recommend you run it through about once a month.

8. If the cooling fan breaks or runs slowly, it's just a computer fan that can be replaced by somebody who's comfortable assembling their own PCs. It's also possible to oil the fan bearings with mineral/baby/fan oil by removing the sticker on the center and getting at the rotor.

9. Unfortunately, even if you do all of the above, the life of the machine is ultimately doomed by the water pump I mentioned in item #1. Eventually its bearings are going to give out. It's not impossible to replace, but finding the right pump model may be difficult. You can't really ask a repairman or the manufacturer to help with this if it's past its warranty; the repair cost would exceed buying a new machine. This is about the most serious problem that any non-defective individual machines could have; something is going to die way before the compressor or other refrigeration components could start developing problems. It's just not built to be repaired.

Also be careful about spilling beverages on it; you'll have to pop open the inner casing of the door to clean up any liquids that seeped through the cracks, otherwise you'll have to stare at stains through the viewing window forever.

All this sounds dire, I'm sure, but as long as it's alive it gives excellent, dependable service, especially for the price.
