We've been using Nitropack for over 5 years on two websites. The system give great results once it's configure correctly. Does take a little work to help it decide which components not to optimise. The support is great these days and provided you can explain the problem and demonstrate it, they will fix it. When you have Nitropack configured correctly it improves website performance no end. Also quite a cheap way to deliver data to users so you're not using up your quota on the web server
