Short life span
Color: Piano Black
We really liked this ice maker. The good-the water reservoir and ice basket are larger than in our last one, so we only refilled this one maybe once a day (family of 4). The ice didn't build up on the side and trigger the ice maker full shut off like our previous one. It is quieter than our last one too, and seemed to make ice just as fast. The bad-it doesn't turn itself back on as the ice melts and refills the water reservoir. The really bad-we've only used distilled and RO water in it. We've been fighting with it for a couple of months now to get it to make ice. We've cleaned it over and over with the cleaning solution. We also cleaned the vents as suggested with a vacuum and compressed air. It's to the point that it literally makes 2 ice cubes every time we start it, and that's it. We bought it 6 months, and we're giving up on it. We'll try another brand.

Almost Perfect
Color: Piano Black
Came from another ice maker and I miss two things: 1) size. This unit is tiny. It might be good if it’s just for you and maybe one other person, but for a family of four where everyone uses ice for their drinks and water bottles around the clock, this was constantly empty and needing more water. 2) the ability to start making ice on its own after there’s enough water. It has a sensor to tell you when it’s full of ice and it has a sensor to tell you when the water level is low, but it doesn’t have a sensor to tell it when the water has been refilled. You have to push the “ice making” button twice to get it to restart. Not a huge problem, but if you’re like me and leave your ice machine on 24hrs a day, you could come back to an empty ice machine after the ice in the basket melts. With my old ice maker, the machine would sense the water was low and stop. But then all the ice that was already made and in the basket would melt and fill the reservoir again and the machine would sense that and start back up on making a new batch small gripes, I know. Overall, it’s a nice, cute little ice maker and my kids love nugget ice.

Compact, lightweight, and useful milk frother.
I ordered the Electric Handheld Milk Frother in the Starlight Black color. I don’t drink coffee, let alone fancy coffees where I would normally need a milk frother, so I bought this for one reason and one reason only: scrambled eggs. I make a ton of scrambled eggs. Now, I can whisk eggs by hand just as well as the next person, and I’m not entirely convinced a frother whips them better than I can, but regular whisks take up a ton of room in my drawers and this does not. I really just wanted something compact that could whip my eggs into a nice frothy consistency without taking up much space. Even better, this one looks nice enough to just leave sitting on the counter where I can grab it easily. I will note that although I can hand whisk easily enough, there are many people who cannot due to arthritis or other issues, and this whisk is a brilliant tool for them. If you actually want to use a frother for other things, this one does perform very well. It has three speeds and comes with three different attachments: a spring whisk for latte and cappuccino foam, a balloon whisk for eggs and cream, and a hook whisk for blending protein powders or mixes without lumps. I actually ended up using the hook whisk while making pot roast. I mixed the seasoning packet with water using this frother and it blended everything perfectly with no lumps at all. The frother itself is lightweight, pretty quiet, and very easy to clean. The attachments detach easily and just need a quick rinse under soapy water. It also comes with a magnetic wireless charging dock that uses the included USB-C cable. The docking connection is simple and secure, and charging has been completely hassle-free so far. The LED display shows battery levels at 25%, 50%, 75%, and 100%, which is useful for knowing when it needs to be charged. Overall, it’s a simple, convenient kitchen gadget that does exactly what I wanted it to do and I am quite satisfied with it.

Works great and easy to use
Kitchen gadgets have a way of accumulating. You buy them with good intentions, use them twice, and then they live in a drawer forever. This milk frother is not that. It's one of those rare small appliances that earns its spot on the counter every single morning. The wireless charging is the feature that sets this apart from every other handheld frother on the market. No fumbling with a charging cable, no little dock that takes up extra space — just set it down and it charges. It sounds like a small thing until you've used it, and then it feels like the obvious way every handheld kitchen tool should work. The fact that it charges quickly means you're never waiting around or reaching for it only to find it dead. Three speed settings give you real control over the result. Low for gentle mixing, high for a proper thick foam that holds up in a latte or cappuccino the way it should. The stainless steel whisk feels durable and substantial, not like something that's going to bend or corrode after a few months of daily use. The whole thing is well-made in a way you notice immediately, solid, balanced, and built to last. The Starlight Black finish looks sharp, too. It's sleek enough to leave out without cluttering your kitchen aesthetic, which matters when you're using something every day. If you make lattes or cappuccinos at home and you're still shaking a jar of milk or settling for flat foam, this is the upgrade you didn't know you needed. Easy to use, quick to charge, and genuinely well crafted.
