Okay so I know that there is quite a bit of software that will allow you to do user testing a lot cheaper these days than in a studio, but I hadn’t come across http://www.usertesting.com before. I used them today for the first time and they were quick, taking a day to have 5 tests done with video and written reports.
The reports I got were excellent, backing up the problems I know one of my sites had. The reviewers were good and explained their problems well. Only problem was probably that they seemed to be quite experienced internet users in some case, even though I had asked for moderate or beginners users.
Overall I would really recommend anyone do this as it only costs about $25 for a test. A bargain for the info you get.
