Many glitches in updating info
By Thomas H.
Sales is inept. Does not read full request to note a special unit. Sends request to engineering where it languishes until I call to check on it then I receive the quote in 30 minutes. After order is placed next email places a hold on the order as apparently there is a nominal setup fee that was not included on the quote!

I placed an order on line to ship RED. Tracking number should have been included with emailed confirmation.
