It is beautiful, it has double blades, it cuts well. The silicone ring is indeed dangerous to be cut, but if you pay attention to it, I believe it can withstand. However, it seals the container and can be washed by hand.

NEGATIVES. The blades need to "lock" together and then on the rotating axis, this can be done by holding a cloth otherwise you will get cut. The same goes for the "unlocking" that needs to be washed. This alone makes it dangerous. This is an important reason not to buy it.

It is not user-friendly at all. The silicone base comes off from its position, the sealing silicone for liquids does not fit properly when cutting, and also the blades do not cut while it is locked, it takes a lot of time to find the right position.
