Question about Caso Vacu OneTouch Eco set

we have the set. it is really practical. i was also very sceptical, but it has convinced me that we have now reordered bowls. we need the bowl to store prepared salads (cucumbers, carrots, etc.). or we also use it to store leftovers. it is also great that the bowls are suitable for the oven.
we use them all the time....
The bags don't convince me that much, but they were there.....
