USB Socket keeps breaking from PM3

[JamesBombed]

Anybody else having had this problem and found a good solution?

I use rowpro with my erg. For the second time in a little over 2 years the cable socket on the PM3 has got loose. I am going to take it to be soldered back on again, otherwise I would be rowing staring at the bomb shelter wall for 40 minutes every morning. Very interesting wall - reinforced concrete with white emulsion.

Did anybody else come across this problem. Did you resolder it with some turbo charged solder, place it in a frame or anything that successfully stopped it happening again?

All suggestions gratefully received. Most clean suggestions will be acted on.
