“Support has been great. They’ve always been open to how we do things—or want to do things—and they’ve made those adjustments the best they could.
They’re really open to listening, and that means a lot. When our old supplier got bought out, support disappeared. With TAP, it’s been the opposite—they listen, adapt, and back us up 100%.”
