Total disappointment
Total disappointment. I ordered Lexus luminous beverage coasters. The package in which the coasters were delivered appeared to have been previously opened and all pieces appeared to be therein, including the charging cord, and there were no instructions included therein. The backing on one coaster was partially separated from its case but otherwise intact. I tried twice to charge the batteries with the enclosed cord and my computer alerted me of overheating and the charging cord was extremely hot to the touch. I have abandoned any charging effort and plan to return the items as soon as I research procedure for same.
