The knives are not sharp, they are thick and on both sides they seem unsharpened. It is not easy to put them together and open them again to wash them. The lid does not lock with the mechanism. It takes 2-3 tries (you search blindly until you feel it locks). It cannot grind a small amount (e.g. an onion) at all. I had to buy a second one.
The only positive thing is the glass container that is easy to clean and does not retain odors. However, the weight is still a problem if you want to take it with you on a trip to grind baby food

The worst purchase ever. I wasted my money for nothing. Firstly, the knives are not sharp, they are thick and on both sides it seems like they are not sharpened. Also, it seems easy to put them together and open them again to wash them. The lid doesn't lock with the mechanism, so I put it in the wrong mode 1 or 2 times, and the third time I used it, it melted and now the knives don't turn at all. I tried to grind 2 slices of toast and it got stuck. Completely useless.. stay away

I read the positive reviews it has received and chose it, but I won't give it an excellent rating. In the positives, I note the large glass container, the fact that it doesn't make much noise compared to other similar devices, and that it grinds the food very well. In the negatives: the container does not have a ml indication for someone who wants to grind a specific quantity of food. It has a separate non-slip base, without which the container is not stable at all. Cleaning is difficult, like most multi-purpose devices, and it requires special attention when attaching the blades. The lid, although it has a rubber seal, does not fit properly and I have to press down on the top to prevent liquids from coming out. Note that I use it once a day for baby food, so I haven't put it under much strain in the two months that I have had it.

For the price of 25€, I don't believe I would find anything better.
Positive
glass container
waterproof
option for 2 or 4 blades
good construction
tolerable noise
there are 2 spare parts for the rubber that holds the blade axis in the center of the lid
Negative
the section with the additional blades attaches to the main component but then it is difficult to remove
cleaning in the empty space that fits on the axis may require a small brush, and where can you find one so small if it is not expensive in the market
the rubber floor used to prevent the container from moving does not cover the entire bottom
it would be useful to have a spare part for the rubber that seals the lid peripherally during impact

I was looking for a food processor for a long time and I saw a comment here and thought let's try it.
Glass container, it cuts everything. Worth the money. I was saved.

The best there is in a blender. A friend recommended it to me and it's really worth its money! With a glass container, very powerful, quiet with no leaks. I highly recommend it.
