I’ve been using it for over a year, which equates to approximately 2200 hours of using it in Arma. Although I agree that the clip isn’t particularly robust, as long as you’re not throwing or dropping your headset while it’s attached you shouldn’t have any problems with it.
Unlike most ppl that I’ve talked to, I even use it as infantry. After a while, you’ll get to where you can’t stand playing without it. It’s extremely convenient (and helps with immersion) to be able to just turn your head in real life to look in a direction. Most of the time using your alt key is not a big deal, but there are times when you’re already doing multiple things with your hands when you also need to quickly glance over your shoulder (ie leaning to the right which is done by leaning you real head to the right while pieing a corner and you need to transmit on your radio (so no voice activation) and you need to glance to make sure your battle buddy is in good position before continuing to move). Obviously that’s a very specific example, but there countless times where being able to glance without having to stop my hands from doing something else has been very helpful.
One trick that I’d recommend (at least as infantry) is make sure you have a reasonably sized dead zone, where you have to move your head more than a fraction of an inch before your it responds. Otherwise a couple things will happen. First is that it will become very annoying very quickly how often you have to hit the key to have it reset to where your current head position is looking straight ahead. Most ops I never have to reset that. But when I first started I had the dead zone very small, and I was hitting it every several minutes. The second reason it’s helpful is if you shoot without sights sometimes (which I rarely use anymore for the 40mm for example), if your in game head isn’t looking straight but rather is looking slightly to the side, no scoping becomes way, way harder to do accurately.
Good luck with it. You’re right that there’s a learning curve to get used to it, but once you do, you’ll never want to go back.
