Frequently Asked Questions

I don’t understand something in a training module despite reviewing it several times, can someone help me?
Absolutely! We’re here to help you be successful, please reach out to us on our support page and we’d be happy happy to work one on one with you!
Can I sterilize my The Cube?
No – full sterilization (Sterilizer, autoclave, cold solution, milk bath, etc) will damage The Cube! Only disinfect The Cube by wiping it down between patients. The device is made to tolerate wiping, but do not saturate the surface.
Do I throw my sticky pad away after each use?
Nope! The gel pad is intended to be reused over and over. If you ever lose stickiness, just wash it with some warm soapy water and let air dry. Be sure to do this with clean/sterile gloves! Also, if you need you can purchase additional gel pads on our web store.
How do I know if The Cube is charged/charging?
The Cube will show a red light when charging, this light will go off when it’s charge is completed.
I can’t get my lights to stay on! Is my device broken?
Maintaining a 110 degree angle when sharpening is hard, The Cube will help you build the muscle memory to do this correctly and it takes time! Continue to practice if you’re having troubles. Of course, if you feel your device is defective; please visit our support page, we’re here to help!
How do I calibrate The Cube?
The Cube will auto calibrate itself when turning on. No need to worry about any manual calibration.
When will more training modules be available?
We’re currently working on additional sharpening modules! Next up will be Sickle which we plan to release in Q1 2020.
