ad 3 Way overpriced, more than double what I was expecting to pay. I bought a no-brand version last year, but after daily use it died. Went with this name-brand, but only because there don't seem to be cheaper options on Amazon at this time. One advantage of this one over the last: You can slide the connection device in and out of the control easily - in the original, you had to open the battery housing. If you PowerPoint, then one of these is a must. I only use the forward, back, and black screen functions. How will this device fair? For the price, it better last two years.
