Pros:- If your outlet is on the wall (as opposed to on the baseboard like with some older homes), this extension cord is perfect. Furniture can be flush with the wall.- Can put 2 of these into each outlet because one does not interfere with the otherCons:- If you are looking for an extension cord for 3 prong, this will not work for you. The end of the extension cord head contains 2 outlets on one side and 1 outlet on the other. The 2 outlet side does have a plastic cover if not in use.Don't know why amazon sells it for so much more than the bull's eye symbol store.
