VicTsing Wireless Presenter, 2.4GHz PowerPoint PPT Clicker, 98-ft Wireless Range Presenter Presentation Remote Control, Presentation Pointer Red（Power＜1mW） with Anti-Lost Magnetic Mini USB Receiver

It works if you point the wall,a black screen or a black frame,but on a white screen is barely visible and only if the direction of the pointer is always 90 degree respect to the screen.So it is not usable for presentation on the screen.It is very light.Arrows to scroll slides work.

Easy to carry-around - fits in shirt pocket. Good value. My only complaint is that the button which advances a slide should be the first button and not the second one.

Tuve dificultad para abrir el compartimento para colocar la pila, buena recepción de señal. Excelente relación precio-calidad.

A reliable clicker but with an odd problem. Because the surface is smooth (very sleek, no doubt), it is hard to tell where your finger is on the device. So you often have to look at it to see if you are moving slides forwards or backwards. I would prefer buttons that you can recognize by touch.

Another dud. Lasted through 4 presentations before dying. No communication

I liked the price but the reason is the comfort of buttons, mush Eisner to use

doesn't work I teach with power point in a big tv and I try to show the pictures to point the detail, but omg you dont nothing. Don't waist your money

My son-in-law got both of these.
