My husband and I used these to hang a few very large dry erase boards (diy'ed out of smooth surface pressboard) in our home office. These strips were easier than ABC to use.

Power for all but the most power hungry gaming systems. Runs a pc, modem, router and monitor (right at 900W) for an hour with no issues.

No issues through three power outages in the six weeks I've had it hooked up.
