Good point. Also in the last year, little single outlet switches that
fit neatly between a two wire plug and receptacle have appeared on the
market. One is made by Leviton. I've not yet seen that for three wire so
the outlet strip is a better option. Outlet strips with totally flat
faced receptacles tend to be poorly made inside using thin brass strip
for the power conductors, while those with sculptured receptacle faces
tend to be assembled from standard outlets connected by copper wires. At
least for those in metal cases. The molded all plastic ones may not be
as high a quality. Unfortunately the UL label is easily forged.

I use outlet strips for my cordless phone base station, my computers, my
cell phone charger, kitchen appliances, and my DVD player. So I can
switch them completely off. My work benches were wired with master
switches decades before outlet strips were made small but often use
Wiremold outlet strips 6 or 8 feet long.
