Low cost, easy to use, seems safe for low power.

I know it's 2025 and every outlet on the planet should have a ground. Unfortunately occasionally I find an outlet without a ground and most of my plugs require one. These are inexpensive, basic, low power adapters that work fine. I don't know if they would work well at high amperage. For running a lamp, laptop, small PC and small stuff these are easy to use and seem safe.
