This is a great little bit of kit. Costs much less than real track IR and works great.
Definitely worth playing with If you like racing games or flight Sims.
Works great with elite dangerous.
My only gripe is I wish the USB cable was detachable at the LED end, so I don't have wires trailing around while I play my non track IR games, cutting and re applying a zip tie each time isn't a great solution.
Other than that it's great.
This is well made and worth the money it works perfectly. This is my best recent buy and I would recommend this product to anyone who uses a head tracker.
A definite upgrade from the reflection type.
The bulbs slightly protrude so it doesn't get lost from the pick up device but are not noticeable, infared light is not picked up by the human eye so it is user friendly and has made my tracker more responsive I'm very happy with this product.
