The "good old days" ??
I'll have to check them out. I re-wired the little spare bedroom so maybe I'll try one in there first. This house is 1955. The spare room is 10 X 12, I tore out the button board and plaster and put in 1/2" drywall. Funny, the button board and plaster I removed weighed 2100 lbs.
holy crap.
just buy at Costco and try it for 30 days.
