Anyone ever use this drain plug?

The LPE designed magnetic drain plug is truly the first no mess, easy to use chip collector. A unique one way check valve keeps oil in the pan while allowing inspection of the chip collector. Also available, the Quick Drain adaptor which snaps into the drain plug and allows easy draining of the pan without unscrewing the plug to eliminate possible spills. SX drain plug kits fit most SBC and BBC applications including L98 & LT1 with non metric 1/2" drain plugs.

Seems like a good product idea....
