In the episode "Good Copy, Bad Copy", Albedo has an Omnitrix of his own, which is an exact duplicate of Ben Tennyson's, except since he was Azmuth's former assistant, he is probably more trained with it. When he and Ben's Omnitrixes meet though, he turns into a discolored version of Ben. Azmuth then scolds him for making a second Omnitrix, because there is only room for one in the world.

The fact that Azmuth states that there cannot be more than one Omnitrix in existence, opens controversy to why no repercussions were taken when Ben 10,000 created Kenny's Omnitrix.
