Good afternoon Dave- I've got a couple of these and the non military version FRK-L. They're good units with big Rb cells in them. They last a long time. Also you can actually work on them. Surface mount components inside. It's worth more than 5 pounds that's for sure. From what I've read the cell was capable of being replaced while the unit was running although I'd probably not try that!
