Easy and free

Can take awhile to begin when using the free plan

Browserling has a pretty great secret sauce that let's you interactively check the looks and functionality of your pages in specific browsers (and you can even pick the versions)

Getting started can be hard. When you ask for a free trial you get added to a queue with everyone else which is pretty lame. We just ended up getting further and getting better support from other products.

Ability to do QA on all browsers easily without having to use different computers.

If you want a an easy interface to test your application on all browser types and operating systems Browserling is the platform for you.

The loading speed can be quite slow sometimes but can't complain about the price of the platform. The interface is old school but it does what you need.
