Great little convenience item !!!Make ice quickly, and quietly. With a machine that take up just a small amount of counter space. Just add H2O !!!The ice machine does make some ambient noise when in use, and when done the sound of moving parts inside paired with new ice being added to the removable ice bin is all you will hear.This machine does not refrigerate the ice that it creates. It will store it till it melts back into water, which will then be created into ice again. if you leave it plugged in and on it will continue this process over and over, until the water needs to be refilled, or it simply stops working. I would suggest making the ice you need when you need it, or make it and store it, then turn the machine off, and unplug it.The only thing that I have had a problem with is the lid which opens on the top of the device. It is quite bothersome when you are trying to access your ice. it opens to a point, to were it is standing straight up, and is not allowed to lean back, causing it to fall forward when you are trying to shovel ice out with the included mini ice scoop. I solved this problem by covering my ice machine with a towel, and when I open the lid I just place the towel over it, when it is in the open position. It works, and The lid no longer unexpectedly closed in the middle of me accessing ice.Another note for would be owners of this contraption, is that naturally, as the machine makes its batches of ice, the longer it is left to do so, the larger that ice cubes become. I am assuming that this is due in part to the cooling coils becoming more cold after each batch, and also that the water is somewhat becoming more cool, as it is turned into ice , and melted = cold water lol.This particular machine offers two setting small and large, in reference to the size of ice cube you would prefer. I leave mines on large, and have not tried the smaller setting yet.These ices cubes are great for use in water bottles, and Hydro Flasks, and will fit in most openings. I have even fit smaller ones into plastic water bottle openings ( one-by-one ).I have no gripes with this machine, and am glad that I decided to invest in one, I no longer have to sacrifice, frezzer space, nor do I have to buy bags of ice, unless I'm filling a cooler for the beach.
