I have used their products since version 1, i was using the "Theia" from 2007 till 2012. It was a great product. But after v1.5 (i think) there was major changes to the UI/UX, the customer support was not as good, and the prices were increased quite significantly. So, I switched to Mango, another vendor offering similar products. After 6-7 months, i am still using the Mango platform. And it has a much better UX and the Customer support is much better. So, I would recommend anyone to use Theia 2.0 or Mango (Mango version 4.0).
