I work full time with dogs at my job so I have seen soft kennels of just about every type over many, many years. This kennel/vehicle carrier outclasses everything I have ever seen! Very well-designed, structurally sound (stronger, more reliable frame than the others by at least a mile), nice looking, and beyond convenient!! Several options for in and out, the fold down/roll up flaps actually stay put when you adjust them, and there are multiple options for secure attachment of my vehicles' seat belts. This kennel stays secure in both back and front seat of my pickup truck as well as any of the choices in my rather small sedan. Outstanding!! (And my dog loves to ride in it, just leaps right in!)
