I recently started making matcha tea at home and opted for a milk frother instead of the bamboo hand whisk that is traditionally used for matcha, due to health issues. I have a connective tissue disorder and early osteoarthritis and need to protect my wrists, so the hand whisk would be risky for my daily matcha habit. The Vomelon frother is perfect for mixing up my matcha tea powder into my water or almond milk while saving my joints from further damage.I liked the included cover for this model, and the large on/off button on the top of the device. Other models have their switches and buttons placed in odd places that could be awkward for me. I have trouble pushing this device's button with my thumb, even though it seems designed to be done this way, so I typically use my index finger to switch it on and off. This works well for me. You don't have to hold the button while it's on - it stays on until you turn it off - so that helps.The two coil attachments are nice, too. The single coil one does a decent job, but the triple coil really blends up well, and froths up my almond milk into a airy, frothy cup rather quickly, if that's what I'm going for.It uses 3 AAA batteries, and I worried they would get used up with daily use, but I have been using mine daily for about a minute or so each day (I blend my matcha, then rinse off by blending clean water and then spin dry before I store it) every day for about a month now and it's still going strong on the original batteries. I am ready with spares for whenever they peter out, though. I checked the battery chamber to make sure I knew how to switch them out, and it's very easy. They are stacked in the end of the device, so you just twist off the end and slide out. There is a holder for the 3 batteries, so you pop them out/in and just slide it back into the main housing and twist it back on. The +/-indicators show which way to place them. I believe it's 2 one way and one the opposite way.The attachments simply hold onto the spinning bit with tiny grooves in the spinner that fit snugly. They don't click into place or anything, but I have had no trouble with them feeling loose or anything while in use, as long as they are fully in place. Just slide them all the way in and you'll be fine.Overall, this works well for my matcha tea and milk frothing needs. I tried it once with an egg to see how well it scrambled, but I used the single coil attachment and it seemed to slow down a lot in the gooey egg viscosity, so I can't say I would recommend it for scrambling eggs, especially if you are doing more than one at a time. However, I only tried once and only with the smaller, single coil attachment. You may have better luck with it if that's what you're looking to use it for.Overall, I'm happy with my purchase.
