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!

Whips as good as my Nespresso Aerocino!

Love this frother. Whips milk as good as my Nespresso Aerocino! I have tried several that just made light foam, but this one is wonderful. And, rechargeable also. Charge lasts a very long time. Great for travel!

Solid Upgrade, Needs Color Variety

Replaced my old frother with this one and it's a solid step up. Seriously, better build quality, more features, and noticeably more control. The variable speed dial is genuinely useful. Being able to dial from low (protein powder, matcha) to high (thick cappuccino foam) feels like an actual upgrade. The three whisk attachments give you flexibility depending on what you're making, and the included stand is a nice touch. Helps keeps the coffee bar counter from getting cluttered. Battery life seems strong so far; one charge has lasted through multiple weeks of daily use without issue. Pros: - Variable speed dial works well across a real range (not just "low" and "high") - Three whisk heads included — good for different drink types - Stand included; compact and stays put on the counter Cons: - Singular color option. The mint green clashes with everything on my coffee bar setup; wish there were neutral alternatives. ANY alternatives! - Everyone may not like the price tag but it wasn't out of my budget and the included extra bits made it worth it for me. If your kitchen palette doesn't fight the mint green, this is a capable, well-built frother at a decent price.
