I'm going to start out with the only flaw that I've found with the frother in the 2 weeks that I have been using it. The Min and Max lines are extremely hard to read unless you have a light shining directly on them. Even in my bright kitchen I can see it until I go to pour in milk and then of course the milk carton casts a shadow over the line and they practically disappear. I'm still giving it 5 stars though since it doesn't impact the performance of the frother because once the milk gets close to the line it starts to become visible again. So if you pour slowly you will never overfill.Now on to the important part. This is an awesome little machine. I have been using for 2 weeks straight now since I first purchased it. First, I tried out using the whisk to see how well it would produce foam and I was pleasantly surprised. It produced the perfect amount of foam for a cappuccino. The frother also had no problem producing this foam with regular cows milk and with the HEB (local grocery store) Unsweetened Vanilla Almond Milk. I have also tried Silk Almond Milk with the frother but it didn't as well with that brand in making foam for a cappuccino.I have since then switched over to using the stirrer part of the frother as I prefer latte's over cappuccinos and I don't need all the foam. This part works exceptionally well with all brands and types of milk, even chocolate milk and chocolate almond milk. It takes about 3 minutes for it to heat the milk and it produces the perfect amount of foam on top for a great latte. When using the chocolate milk it doesn't create foam at all which is perfect for a mocha.I have also tried the cold stirring for iced coffee. It does this just as well as it does the hot.On to cleaning. I wish I could give it more than 5 stars on the ease of cleaning alone! It is very simple to clean out. The almond milk I use does clean a tiny bit easier than regular cows milk, but even that is still easy. After frothing or stirring, I simply run water into the frother and then wipe it out with a paper towel. It's that easy. I've never once had to scrub or exert any amount of force to get it clean. In my usage, I have found that it's a lot easier to clean out the frother after cold stirring or frothing, which is nice.One thing I haven't tried yet is using the whisk with heavy whipping to make whipped cream as I read that it could in another review. I will update the review once I've had a chance to try that, but even if it doesn't work that well it still wouldn't detract from my 5 stars.Bottom line: If you're looking for a milk frother, this is one the one you need. No frills and thrills, but it does exactly what it's supposed to do, and it does it exceptionally well.UPDATE: After using this frother for 6 months now it continues to be a workhorse in my kitchen. The only other appliance that gets more use than this is my espresso maker itself. Even after 6 months, my only complaint is still how dark the fill lines are. I have even left milk in the frother overnight by accident that dried. Filling it up with water and letting it sit for about 10 minutes allowed me to simply wipe it out with a paper towel.Overall, still one of the best purchases I have made on Amazon.
