What do you think of a magnetic drain plug?

IMO, the valves creates an unnecessary constriction to the oil flow during draining. Judging from the picture the hole has about 1/4 the cross section of drain pan hole. The faster the oil can flow the more sludge it can carry.

One touch operation doesn't sound like a selling feature. I don't want my oil to drain out of my engine with just one touch. I'd feel safer knowing it took a few deliberate steps before it came out.

rod bearings and rings likely contain iron, metal filings from these would indicate an issue.

If one really wants to make draining the oil easy, the best product is a Femco oil drain valve. It requires a mating drainer, doesn't hinder flow and will last the life of the vehicle. Far superior to the other product, these are commercial grade units designed for trucking and heavy equipment applications but also available in thread sizes for passenger cars and light trucks.

The problem with a system like that is if you are traveling or want someone else to change the oil, e.g., you need to take the drainer along and tell the tech how to use it.
