Review (1/5): I bought this item and when the original item came ...
I bought this item and when the original item came to me it had a toothbrush already attached to the main electrical unit. The package also included two other brush heads. When the original toothbrush that was attached to the main electrical base unit wore out I tried to use other two that were included in the package, but they had a different attachment than the original electrical base unit. The two included toothbrush head replacements were different from the original toothbrush head already attached to the main electric unit in the original package. So tell me how do I attach the two brush heads that were included as replacements which are different from the one that was originally attached to the main electric body in the package.
