Questions about Isofix-Base Comfort Fix

I'm not sure if this is the right Isofix station. The Shopper slx comes with the Zero bite child seat. We had the Comfort fix child seat. The station worked well with this seat. I would do some research on the net to see if there are any test results for the Zero bite... Hauck also has bad child seats. The Comfort Fix passed the test with "good" as far as I can remember.
