As a small blender this seems to be really good. I've mostly used it for smoothies and sauces, but some have involved frozen fruit or vegetables which it has had no issues blending well.
There are just a handful of things I don't really like: - There is no lid provided for the plastic cups, meaning you can't just stash some or all of it in the fridge afterwards, you need to transfer it to something else that seals. - The blades are really quite hard to clean properly. Maybe this is a trade-off between good at blending and hard to clean, but it takes some effort to get under the lower blades in particular. - It's a pity it doesn't come with a bigger cup.
