One of the key points to a great extension is the support. The support is excellent and they are doing a great job! Once you buy this you won't need another slider...and it's only $30!! That's nothing.
Keep up the good work guys and thank you.
The demo didn't install properly for me but I still decided to buy it. The bought version installed perfectly and works great.
One negative point is that there is no support contact, just the forum. So if you need a quick reply then you might be in for a wait. I posted one issue and it was answered in under 48hours, so I guess that it was reasonable.
