They may be rare apart from in my house... i have 104 :rofl2: all in full working order except they all have broken hinges.
I brought them with the intention of fixing them, but the supplier i intended to buy the new housings from stopped doing them :rolleyes: now instead of shells being £4...
How do you mean "mushy" sometimes after they become well used, the up/down/left/right arrows become less responsive so the rubber behind them can be replaced.
If you mean the "L" and "R" trigger buttons, they can be cheaply replaced.
