PI Manufacturing 3 Prong to 2 Prong Grounded Electrical Adapter, UL / cUL Listed - 2pcs/pack by PI Manufacturing

These outlet converters are exactly what they say they are. My apartment is over 100 years old, before grounder prongs were commonplace. These. are fantastic. I recommend these from PI Manufacturing

I could plug each of them into the outlet but I could NOT plug anything into them.I threw them in the trash bin.

Same plugs that have been around for 20 years, they work just fine and do the job for an ancient outlet I have. One of them didn't work and I couldn't get my laptop cord into the adapter. Looking on the prong holes I can see some metal is bent in. For seven bucks they should both work.

I ordered a few sets of these. As I now live in an old house (that has been made into 2 apartments) and have a need for numerous 3 prong grounded units but walls have only 2 prong, these has been a life saver. Wonderful to have.

Doesn't work. Cannot plug anything into them. Prongs from my device will not plug into the adaptor; it's as if the openings are blocked inside. Not sure I can get a refund from Amazon. $6 down the drain.

I purchased these to use on one outlet. I received two-one is a spare. I am using it now and nothing has burned down. Fast shipping and aquality product.

Needed for spots that don't have a ground plug option.

They have a polerised configuration. They do the job. Standard rubber case.
