I just wanted to let you know that the five prototypes of the Glove 3.0 Main Board you built worked great. No errors and completely functional. Another exceptional job.  Please let everyone know that this is why I use Ninja for our prototypes. I believe you have or will be receiving the P.O. for the remaining 25 units.
