Highly unreliable I mainly got this for rendering stuff my pc couldn't and it can't even do that most of the time. It just refuses to respond in simply opening the file (when the specs it boasts of should be leagues ahead of my pc) and then kicks me out asking for more money. Horrible product imo however for the 10 percent of the time it works it does work as promised but what is the point if I'm basically gambling??
It's by no means a perfect solution, but it is a great idea and when it's working smoothly, it's really good.
Customer support is quick to respond to issues and it is very straightforward and easy to use.
