First off they have a great, professional product, I've purchased many products from Pixel Studio's to make great Digital Video Productions. I was having a problem with ProTiltShift, the mask wasn't working. To fix it they GAVE me a complimentary plugin, FCPX Camera. I was still having problems and couldn't get the mask to work. A Pixel Studio's professional shared my Mac and fixed the problem quickly. This was a JOB so I appreciate the time and effort from Pixel Studios. Simply the best!
