Just wanted to let everyone that Brett Davis is an awesome guy to deal with! My xpin power supply went faulty tonight and took out my dmd in the process. I sent an email to xpin support and within a hour brett davis gave me a call and we trouble shot my power supply..long story short, he is sending me a new power supply and a new green led dmd! Kudos to you Brett, I was already a loyal customer..a power supply, a led dmd, and just got a new white dmd today, but after his teriffic support after the purchase, you have earned a lifelong customer and tons of respect from me. We need more men of your caliber in this hobby!
