The fact that the tool is highly configurable allows complete control over which optimisations you choose to implement. With clear explanations of each option you feel in complete control and know exactly where some issues may arise and what to look out for.
I had some issues initially due to some custom code included in our site but our support request was responded to very swiftly and the issue successfully resolved.
I would highly recommend this add-on for its implementation and the results it can achieve but also for the super support should you have any issues or queries.
Had an issue and support was very good and very quick. He found an error in some of our html which was throwing off what Instant Page Speed Magic was doing.
I highly recommend this if your site is having some responsiveness issues and/or you want to improve usability scores.
Great support with awesome results
Brilliant tool for speeding up Concrete5 sites (A LOT!)
Support is great and help out wonderfully in problems. Thanks!
An Excellent Add-On
I'd recommend this add-on in a heartbeat.
