I really like the overall design. The flat base on both ends makes it easy to stand with or without the top on. The rubber end on the lid is removeable making it easier to clean. The button function is very easy to use even though there is only one speed. Pressing the button slightly without "clicking" it makes it easier to work with if you need less power. I haven't tried it for eggs yet but it works great in lattes, coffee, teas, smoothies, and drink mixes.Cons: It would be nice if the whisk part was longer. If you need to mix something at the bottom of a taller glass/cup you have to half fill it, blend, then fill more, and blend again. Also if it were detachable.While the battery operated feature makes it more portable and affordable, a rechargeable battery would be SO much more convenient. If that became an option I would definitely re-buy this. I bought this one and a rechargeable brand at the same time. While the features are very similar the other brand (button) works in reverse and makes it difficult to control so I tend to use this one the most. It's been a couple of months since I bought it. I use it multiple times a day, everyday, and have change out the batteries once so far. Not sure if that is good or bad on energy consumption. Overall it is a very nice product. Not the first battery operated whisk I've owned but definitely the best.
