Review on Rechargeable USB Presentation Clicker W/ 2.4GHz Wireless Remote - Compatible With Mac, Keynote & Laptops by Jonathan Self

I have used this wireless powerpoint presenter for teaching the past few semesters. I had two other types prior to this one, but this is by far my favorite. It's comfortable on my finger and allows me to hold a dry erase marker and a long pointer at the same time. Not having to replace batteries is a nice bonus also. I recharge it every couple weeks and may be able to go longer between charges, since the laser pointer has always kept working. Lastly, best of all. I recently left the USB dongle in the computer in the classroom last week and it didn't turn up in lost and found. I went online and was ready to purchase another presenter, but saw that the company offers a free replacement of the USB dongle. I contacted Customer Service by email yesterday and received a reply the same night. They are sending out a new USB dongle through revain.
