I purchased this countertop ice maker to replace one from another brand that failed. When researching countertop bullet ice makers I found that they were all pretty much the same exact thing with different brand names. However, there was one feature I really wanted after my previous model did not have it... that feature being a water supply line. This was literally the ONLY countertop bullet ice maker I could find that had it. And oddly enough, it isn't talked about in any reviews and not even in the manual! I was confused how it would integrate with where you manually add water below the basket. Didn't make sense to me how it could work, figured it would be one or the other, but if only a supply line then what happens with the melted ice under the basket? Do I have to dump it? But still, I took a gamble and purchased this one. Well I will explain how it works now that I have seen it in action. It pulls the water from under the basket where melted ice would go. If there is water there, it pulls it in. If there isn't, it will try pulling from there 3x and then since it isn't getting water, it pulls water in from the supply line which trickles from the top down into the reservoir below the ice basket. It fills about 1/3 of the way and then pulls the water in from the now filled reservoir to start the ice making process. Pretty ingenious. Even better than the float switch method I thought it might utilize. Other than that, it is pretty much the same as the old ice maker I had. It does have a bigger footprint which is kind of a bummer, but with that comes an ice basket 2x bigger which is nice. Overall, very pleased with this unit and as long as it doesn't fail it fits my need perfectly. I did buy the 3 year warranty though as my old ice maker (different brand, but probably made in the same factory) failed in exactly one year so not sure if I want to take the risk of having no additional warranty.
