My two both love this and chase it a lot though I tend to find only for 5 or 10 minutes before it loses their attention. It is rather noisy and not quite as random as some of the online pictures from the company suggest so hence it loses a star. The faster speeds are a bit too fast for cats to chase but ok for them to watch it. All in all a good product
Initially as it is quite noisy our cat was wary of the machine, so if your cat is nervous then perhaps not the best toy - try the BOLT. however, after about a week she ignored the base making the noise and started seriously enjoying chasing the laser over all our funiture. A great toy but you may have to let your cat get used to it for a while.
My cat was not in the least interested in this so I passed it onto a friend. Her cat also showed no interest. In the end we gave it to a dog.
