RJSimTech

DCS user here, If you're looking for a wireless solution this is definitely the way to go. The strap adapts perfectly to any shape of the headset (tested with two, a thick one and another much slimmer), is stable and reactive.
The charging requiremenet may appear daunting, but it's just a regular usb charger you may already have at home from other appliances (not smartphones).
Seller is responsible and comunicative, and shipping times as expected (USA to Italy).
Definitely would recommend to friends

Its a MUST for headtracking money well spent.
I can only be sorry that I didnt discovered this before.

The quality is off the charts! Never in my life have I seen anything 3D printed with this level of quality. Very lightweight and easy to fit to my headset.

So far so good

Rjsimtech reached to me that it was lost in transit. They quickly fixed this and it arrived in my hands. It had been immensely good with tracking. I can look over the to the center area of a 747 very well. overall 11/10

Very good quality, works very well along with having a good charging solution. Thank you for the great product.

1.5 years after I purchased my IRTrackStar RS Ultralight the ACTUAL MANUFACTURER, I mean the guy himself, gets on a Discord call to sort out issues caused by other folk's hardware... I mean, wow...

Item came as described and on time as a gift for someone. I have to say that the overall build quality is outstanding. You can barely see the print lines and cannot feel them at all. The person who received this for their birthday informed me that it has given them “the smoothest head tracking in DCS they had ever experienced”. Well done, guys!

Extremely accurate device
I gave up on headtracking until I discovered this one.

I love the performance, the look of the camera. I didn't but his wireless led head tracker too. Hollywood has spent hours helping me set up, trouble shoot and tune my head tracking. he is a awesome dude.

Actually, this has nothing to do with you but my order has been “returned back to the sender” because the belgian post only gives you 7 days to pay the EXORBITANT 40€ tax on my order, I was away and only could do the payment today, 1 day late… I bet it never gets back to you… this is annoying…..

Everyone needs one of these, a beautiful product!

My shipment to Australia just arrived today and I was excited in anticipation. I've been using a Delan Clip upto now but one of the IR leds failed and whilst I cold have replaced it myself I wanted something a little nicer to go with the A-10C cockpit that I'm building. Well, I have to up my game with the standard of finish on the cockpit now to match the irtrackstar. It's a thing of beauty!
All 3d printed but so detailed in ways that are superfluous to actual function but are the essence of a beautiful product, sooo impressed!

The device itself is awesome & feels well made. The frosting on the LEDs works really well as far as you can turn your head it will track it. The only problem is that for some reason my specific set up it's not working quite right, I get a y axis flip when I turn all the way left/right. Despite this I would still recommend this as it is quality & from all other reports I've seen from other owners it works fine with their opentrack software. I intend to try again when I get a new camera set up. A big shout out to RJsimtech on the discord though, they worked with me trouble shooting the problem until we had exhausted all possible ways to fix my specific problem, this dedication alone is worth me recommending this to others.

Absolutely love it turned out great
