Plugged them in all around the house. Still monitoring to see the difference in my electricity bill.

This is good for sideways sockets. I live in an old house in new england, and we have outlets that are sideways horizontally along the baseboard. The ability to turn and arrange it in any direction to accommodate 2 3 prong plugs is a beautiful thing!

Easy to pack snd not heavy. I thought it was a little bulky and flimsy at first but after plugging everything in then plugging it into the outlet, it hold up nicely.

This one is bulky and flimsy. I’m not sure if they ever worked.
