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, 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
Still not sure? Let’s clear that up.

Your sim racing is in good hands
Hi, I’m Luis, founder of BoxOneRacing. I’m a sim racer myself.
I started developing my own Button Boxes because I couldn’t find a product that combined the functions, materials and tactile feel I wanted for my own setup.
Today, we develop, manufacture and assemble our products ourselves in southern Germany. That keeps us close to every box we ship and the people who use it.
From sim racers. For sim racers.
Try it on your rig for 60 days
Use the box in real races, feel the buttons and encoders, and see if it fits your rig.
If it isn’t right for you, you can return it within 60 days under our Test Drive Guarantee.
How the Test Drive worksOver 5000 Simracers use our Boxes
The buttons provide excellent feedback and feels like high quality.
All in all the box and its mouting kit are from very Good quality. Buttons are really reactive
Great customer service, and they look good on your rig.
Great addition to my setup, great value would have liked more mounting options, but, very happy with my purchase.
Simply mount on the rig get on iRacing
Comes with label stickers so you can label the button functions.
Great box and super-fast service, even months after the purchase.
