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.
