Reasonable price but there is not the best technique

The price offer is hard to beat but this one has then Schwirigkeiten use when. The cover does not lift all perfectly and are often pushed back up by the water.
At the first use then the content is below flowed through (which was but probably because I had to temporarily store and they were no longer froze fresh)

Conclusion:
Who wants to make low ice glasses is right here!
But who gets more invested a few euros I guess a more comfortable solution;)
