Yeah, it's me that bought one last April, though mine is yellow and grey.
After nearly a year's use, no regrets whatsoever. Both my cats love it (I only have the one, but may get one from Tesco - it is the same and £10 cheaper than what I paid at Scampers) and it's done many a mile to shows, including the Supreme. It sits snugly in the front seat of my car, belts in easily and is comfy enough for Pearl for long journeys. and clips aside, it is very sturdy.
The only downsides to it is that the handle digs into my hand for a while and that the porthole in the top is actually big enough for Pearl to squeeze through, so I need to be very careful when I open the hatch.
I've not seen any other exhibitors using this carrier, but the duty vets and stewards at shows love it because it is easy to remove a cat from and also to put the cat back in it. I've had loads of positive comments about it.
