No, it is no longer a combination self-defense weapon and keyboard. The buckling spring action itself is still decent but the build quality is much worse, and the melted plastic rivets that hold the membrane have a bad habit of breaking or flexing and rendering keys unusable over time. You can address the rivet issue by drilling with a pin vise and using screws but be prepared to spend a day doing it since there are something like 50-60 rivets. There is someone that was doing a reproduction of the Model F (the earlier and more robust XT keyboard prior to the M) but they're quite a bit more pricey.
