I recently started making glasses just for fun and for gifts, but I hated making just one at a time. My husband found these motors and made a bigger lure so now I can make about 5 at a time! It was so easy for him to connect and install these motors. When we first used them, we watched them closely to make sure they didn't overheat or burn out. You were perfect! They worked about 8 hours and they didn't heat or anything like that. They work great!
