Honestly, I couldn't be more dissatisfied with BestTong. They boast about having top-notch products and service, but my experience with them has been everything but professional. Their industrial switches and other products have been nothing but a source of frustration and failure for me and my customers. And their support staff? I won't even go there. They appear to have little interest in their clientele. BestTong has lost my business and I will never refer them to anyone.
