This extension cord came well packaged and in perfect condition. Is essential to have this short extension cord when measuring electrical values (Amp, Watts, VoltAmperes) with instruments ( such as KillAWatt instrument) that are intended to be used plugged into electrical sockets on the wall or on Surge Protectors.

For some reason, the review process believed that the power strip liberator was a toy, and asked such things as 'how fun is this toy?'. Well, sadly, not very fun for a toy, but a perfectly good short extension cord. These are good quality power strip extenders, offering a a power outlet on a short cord, as well as one on the back side of the plug itself. It works well, and I recommend it for the purpose.

I don't know why Amazon asks me these stupid questions like, "how much fun is this toy" and "how would I rate this toy's educational value." For one thing, it isn't a toy, it's just a simple but practical extension plug that allows you to use a power block on a power strip and not use more than one plug space. I guess it is educational in that if you put your finger in the socket while the other side is plugged in, you will learn something very quickly that you can hopefully live to tell your grandchildren about. The product is sturdily made and works. Not much else to say about it, except it is NOT a toy.

Kill-a-Watt Caution. I checked with the shipper and this cord has a lower power rating than the Kill-a-Watt you may be using it with. To avoid over-heating this cord be sure not to use with refrigerator, washer, dryer, air conditioner or other large power using appliance. Kill-a-Watt is rated 15 amps (1875 VA) and this cord is smaller, about 1/2 the amount of the Kill-a-Watt. We want you to be safe and avoid the classic "extension cord fire" from over-heating a cord.

What a simple yet functional device. Great to use on a power strip or on a Kill a watt device. Gives you a little space and doesn't crowd the outlet. I bought several of them and wish I had a few more.
