I ordered the this portable ice maker after a lot of consideration and reading many product reviews. Some were cheaper and more in the price range I wanted, however I also wanted one that produced ice that didn't melt quickly and produced ice quickly. This ice maker is fantastic, actually the production is faster than I use (I cut off the unit until I'm ready for more), the ice cubes are just the right size to fit in stacked 2x3 rows of ice for my water tumbler and the ice stays ice and cubes don't melt quickly. LOVE this machine, very happy with all it does. It has an automatic shut off when ice tray is full, shuts off if the water level is low, is very quiet, cubes, although coming out in full sheets or half sheets are very easily broken apart by hand. The only time the sheets are frozen too thick to easily break apart is when the ice tray is full and the sheet in the form can't empty and more ice forms on top. In that case, which is rare for me, I turnoff the machine, let the ice in the form melt a little and soon it falls into the tray. I LOVE this machine! I use only filtered water in it, use it every day, most of the day, use ice for my filtered drinking water (I don't like the taste of treated county water or room temperature water), and put cubes in my ice cooler.
My research showed the round bullet ice melts relatively fast, not so these cubes. I drink from my insulated water tumbler all day; I fill it with cubes and water in the morning, refresh the cubes about once during the day and still have cubes in the tumbler by evening. So far so good with this unit, it is worth the price. I'm very satisfied, no complaints on speed of making ice or having the ice expended in the tray in sheets or half sheets--no problem at all, the cubes are easy to break apart by hand. It's compact, fits easily on the end of my kitchen counter and underneath my top cabinets. Water reservoir is filled from the top, controls are on the front and let you know if the water level is low. Very nice machine.
