Been dealing with Brandt Denkers, bd3dcustoms.com , for over a year now. I chose the Hypercube Evolution 445 kit from him, for my build. It was before he came up with the Supercube, and have to say I love it. Have done many upgrades on it since starting the build over a year ago. Brandt has proven to me, to be one of the best, if not The best, at customer service, when it comes to 3D printing. Much appreciate your review, and am sure Brandt does too.
