It's an amazing service and well worth the money if you're spending any time testing cross browser rendering. Especially if you don't have access to all of these platforms. Lets you tunnel locally as well.



Basically it gives you access to VMs testing specific browsers. I love it for IE and mobile testing. It's not unique, but it's the best executed service I've come across. Highly recommended.
