I’ve tried a haptic vest back in the late aughts. Tested it with CS:S if I recall correctly. It was fun until the point blank shotgun blast. Worth a try for sure, but I personally wouldn’t use it more than once.
Out of all the haptic options, this is definitely one of the more gimmicky ones.
For those curious, they’re called “punaise de lit”, which literally translate to “bed stinkbug”, because technically they are the same family as stinkbugs.
Fun fact, stinkbug is also the word used for thumbtacks. Couldn’t find a reliable source on why though.
