Not very powerful but I'd say ok for small amounts of SOFT or very LIQUID food. I got this to make frozen smoothies and it couldn't cope, it mashes the bottom of whatever you put in, leaving a lump at the top that you have to either keep adding liquid to, or keep pushing down with a spatula. I managed to get the right frozen fruit / liquid ratio to get it to work without sticking, but still after a few uses the rotor base and the rubber feet under the blades (that connect to the rotor) have either been torn off or worn smooth. One of my blade attachments is unusable now.
The juicing attachment is pretty poor - it fills up with pulp which you have to keep emptying between pieces of fruit, so pretty pointless design tbh...
If you're only blending very soft, liquid things for one or two people, it's ok. Otherwise it's not really worth it.
