IMO, If your cat enjoys balls, and especially ball in track toys, this one is a great choice.
-my cat likes it a lot
-it seems well made for a cat toy
-it has a smaller footprint than similar products, making it easier for small cats to use and take up less space.
-it is a toy that doesn't require "monitoring" the cat for safety (apparently earlier versions had an issue that has been resolved)
-I wish that it came in colors besides "blaze orange"
-it is a bit light, so when my kitty gets really excited she cam make it move slightly (nothing serious, but you can see it in the video)
