I bought this in May 2023 and it's July 2024. I went on a trip for 6 days and when I came back, it wouldn't turn on. It could possibly be because I've used it every day and suddenly stopped. Either way, I'm disappointed in the longevity of this product. For the price I expected more, but nothing is made to last any more. That being said, I love the design and rechargeable aspect. The cap is awesome for storage and clean up is super easy. This little machine packs a punch as long as you have enough liquid. I've never had issues with lumps or performance in general. I will purchase this product again to see if it was just a fluke.

Bigger/sturdier than expected = good and bad. Recharging cable is USB to USB-C. Need old style brick

I like the design in that it comes with a cover that shields the wand in my utensil drawer but its a bit bigger than expected. So its a plus that its sturdier but a minus that it takes up more space. The USB-C cable is USB to USB-C and not USB-C to USB-C so I had to go fishing for an old brick. Am hoping it doesn't need to charge often. The indicator shows its plugged in but not whether charged.

Good

If this works very well, it is better than the others I have bought.

Got three years out of it. Better than some others. Docked two stars for lifespan. Docked another star for the paint finish which is not durable and marks easily. Should be more like $15 ?

I am very impressed!

This little frother is perfect and my frappé coffee tastes as if I were sitting at one of the hundreds cute, outside cafés in Thessaloniki. It whips stiff coffee foam in just a few seconds, holds charge for a long time, and appears to be of superior quality. Variable speed control is great, as it prevents the coffee liquid to splash when starting the frothing process. Granted, I have only owned it for about 2 weeks, but I am totally impressed, and hope it'll keep making delicious frappés for me for a long time to come. So far, highly recommend!
