A nice basic battery holder. Worked fine to add battery backup to an old 386 computer.
They do the job they are intended for, and are very inexpensive. Seem well enough built that they won't fall apart when replacing the batteries.
I am very pleased with my experience with MCM. The website was easy to use, and has some very competitive prices. My order was shipped very quickly and I received my order less than a week after I placed it.
