Holds Apex probes.
This holds my apex probes. All the holes are correct size. The magnet could be stronger. It holds but is easily moved due to a weak magnet.

Holds well, works as advertised!
Got this to add to a saltwater aquarium to hold pH, temp, and other probes that are connected to my Neptune Apex. For that, it works as intended. Can't complain too much.
