Bathroom Outlet - which replacement brand is best

        I have whatever you call those safety bathroom outlets in my home.  They are over ten years old.  One of them has a window a/c unit plugged into it.  Nothing in the house has changed, but the window unit is shutting off and on too often, and sometimes the outlet shuts off.  I have had to turn it off completely.
       I need the a/c unit to cool my home so I need to get the problem fixed.  Somebody mentioned a specific brand of replacement that had tested best, but I cannot find the post. 
TIIA, Josie

Yes, required by safety code. Every home on the grid has one.

When the outlet gets old, it will do that. Also when in wet and dusty
locations the circuitry will get corroded. Completely normal and
annoying. Even worse in outdoor locations, than inside a bathroom of course.

The manufacturer would say it served it's purpose and is time to upgrade.

If it is in a bathroom, it will have to be replaced with another GFCI

That was me, I found success with Cooper or Eagle brand.
