I am new with cages. So I orderd " The beginner" I loved the feeling, but the cage was too small. I bought the V2 next, with a Large cage. The V2 is much more comfy. But you guessed it, the cage was too big. Every system has its own dimensions, lenght and width, lesson learned. The V2 has a wide cage. That's why I bought this Medium, cage only. Now I use both! You can never have enough cages. I like the locking mechanism, no dangeling padlock. Nice webshop. Good and fast service.
