Presentation Clicker

I've given in and bought this presentation clicker from Amazon for £13.99 - there is a huge variation in prices. This one appears to work well and comes with a drawstring pouch for protection in my laptop case. The one comment I will say is that USB receiver in the bottom was difficult to remove and in the end I had to use a tool to slide in and pull it out. Works perfectly with my Dell laptop and PowerPoint. I was surprised to find my local computer shop didn't stock any brand and was actually quite condemning about them. This one is from Hearmarket.
