Terrible. One of our customers forces us to use Tungsten Networks, and unfortunately, they're a big enough customer that we can't just tell them to find another vendor. As for Tungsten itself, the interface is clunky and unintuitive. We use Tungsten for ONE customer, shipping to ONE location, and that's it, but I have to enter the customer name and the shipping address because it's different from billing...every time. I have to create the invoice in our system, then go and re-enter everything in the Tungsten "system" (those are sarcasm quotes). Speaking of their system, it's actually down at the moment, which is why I'm doing this and not tediously entering invoices after I've already created them once. All that, and we get the privilege of paying for it! Not that it matters to me; I instituted an invoicing surcharge, so they pay for their own stupid decision to switch to crappy Tungsten Networks.
