I order this for my guinea pigs and I'm verry pleased! I did need to add additional stair planks to the ramp for them to climb up and down it better but, even that isn't enough to rate it less than 5 stars! It was an easy set up, it was delivered two days earlier than expected, and the functionality of it works well for the price. I've had it for about 3 months now and still have no complaints.
