The X1 brings my iracing setup to another level!
Some of the cooles upgrades i got for my rig thanks for the boxes
I use it with Assetto Corsa and iracing works flawlessly in both
the perfect balance between price to perfomrance. Genuenly the most quality buttons on a button box that i have ever felt
At first I wasn’t sure if it was worth the money... but once I used it, I got it. The switches feel better than anything I’ve used before. This isn’t just a button box it makes me want to simrace :D
wasn’t sure if the X1 would fit my Sim-Lab rig, but with a few spacers and longer bolts, it mounted solid. No flex, no issues. The buttons feel great, the encoders are responsive, and the LED lighting really pops. It’s now a permanent part of my setup
Shipping was fast the streamdeck was very easy to install made the setup so much more immersive
Your sim racing is in good hands
I’m a sim racer myself.
I know the problems: not enough buttons, awkward controls, distractions during races, and hardware that never quite feels right.
That’s exactly why I’ve been developing sim racing button boxes and accessories for over four years. Not as mass-produced products, but built from real experience. Every detail comes from countless hours in the rig, real races, real mistakes, and continuous improvements.
My mission?
To give you more control, clean workflows, and a focused driving experience – without compromises in quality, tactile feedback, or functionality.
From a sim racer. For sim racers.
