My cat loves it
My cat loved it from day one. He sits at the highest level and observes everything out of the window (best place to put it) and he will nap there, look at birds, look at us, play even eat. The only bad thing is that 1,5 and i had to start stapling in loose rope coming off, now 3 years in it is all wobbly beyond repair, so have to buy a new one. Its around 30e a year you pay, but wish it lasted a bit longer (5 years).
