Solider basket but adapter with pitfalls

The basket itself is made solid and beautifully spacious, Allerding the handlebar comes off easily.
Alone the basket makes no sense, however, since it is designed to be mounted to the adapter!

The adapter has a simple lock, so that the basket can be closed.
If the adapter is mounted on the wheel, he (ie no more worry that the basket can come loose) holds good, is spacious and I never have to worry about me again if I wanted to be stolen-risk or not. That's the good thing about this bag.
Another plus point for touring cyclists could be that can be on this adapter attach additional bags and even a weatherproof closed suitcase.

Now the reasons for star deduction:

1: Installation of the adapter is not easy and if the corresponding adapter is once tightened, Lets In one of them the finger. In my case I had with pliers remove the old spring clip and without the basket the attachment is unusable.
How well the whole holds with the screws in the long run remains to be seen.

2: I can see the bag with the lock firmly close, that's nice, but if I want to take it off are to unlock, and then gotten back firmly get every action with quite a lot of effort. Here cutting systems where the entire rack extension itself is already set up for the baskets can be placed better around lengths from (inziger disadvantage there: not lockable).
