after his wife used a product on a flight from Bermuda.

Victor Kiam, the owner of Remington Products, invested in Cirrus Products, the makers of adapted ear plugs called EarPlanes.

He was persuaded to invest after his wife used them on a flight from Bermuda to help protect an ear drum problem from changes in the plane's cabin pressure.

"Sales are running about six times the level they were last March. I can see a really great future,'' said Mr. Kiam -- famous for telling TV viewers that he liked the shaver so much he bought the company.

The plastic plugs have a filter "which acts as an air lock and gradually allows air in,'' Kiam told Reuters. "This is the only non-invasive preventitive for ear pain, sinus problems, things like that.''
