Considering the price, don't hesitate it. My guitar has never fell down ever since I have it. The same applies to the bassist of my band who moves a lot...
It was very easy to install: I just had to unscrew the original pins of my Les Paul, screw the security locks, attach the other piece to the strap and that's it.
Watch out: in my case, the security lock screws were almost the same as the pin screws of my Les Paul, so I had no problems. But it is possible that they are much shorter, in which case they won't be tight enough and the system will lose its great reliability... In which case, don't try to fill up the hole with wood paste or matches: my guitar tech says it's not reliable in the long term. The best solution is to drill a much bigger hole and fill it with a fitting plug. Afterward, drill directly into the plug with the right diameter. If you are not sure if you can handle this on your own, just ask a guitar tech to do it for you: for such a job, he will charge almost nothing...
