Query: Very Dissapointed!!!

The Pictures of the producst show Crystal Glass balls, but it came with cheap plastic balls. No assembly instruction included. It so poorly design that bottom level ball holder does not have the space to hold all balls comming from top level holder. The bases are unstable, so at the minimum intent to move the toy, it will be necessary to assemble it again.
