I chose between Maxi-Cosi Tobi and Romer King 2, honestly, I did not expect that there would be problems with fixing the chair, but they were successfully resolved.

In the unfastened mode, the straps loosen without effort, in the fastened mode they lock automatically, which is very convenient. According to tests of chairs without isofix, this model occupies a leading position.See full review
