to put this to gether was great when you look at the pics. , but when you look at the screws are not accurate and this print is small. all in all my cats do love this now that i  have three total from pixie. i wish that the toy would last longer my two cats will tear this ball right off , but all in all very stable to hold my 11.5 lb cat and a 10 lb  to jump and play very stable great product
