I was happy with the delivery, but I think you need to improve the product tracking part. Every time I tried to use the tracking from my Email, the tracking when to your website. I just happen to have a UPS website on my computer so I use that site to track my delivery. I have not used your control board.I bought this one as a backup control board because I had already ordered one when I found you guys. I just hope it work find if I need it. Thanks Charles.
