I've got the V2 and it is good, goes up easily, comes down & packs away easily, has loads of room, however, my one bug bear is, having spent years working out their bivvys needed something to stop raining coming in the front door why didn't they put a peak on it. When it rains it's like I've gone back 5 years with the floor getting wet from the drips. TBH I lot like a numpty and make a peak with a golf umbrella strapped to the tension bar. No doubt V4 will have a peake
