RF Wireless Green Laser Pointer 5mW With Page Up/Down Presentation Function-Green Laser

I bought this laser pointer just lately, initially it worked very well, now it doesn't work at all, no laser emission even I replaced with the new fully charged battery, but the up/down buttons still work. I guess the green laser diode inside this laser pointer is bad in quality. I suggest you be very careful with buying something like this from unknown online source instead of directly from Amazon.

works great, bright laser, fair price, uses AA batteries....the only "negatives" I can think of: device could be smaller and oddly the up button is down and the down button is up.

This is absolutely the most user-friendly laser presenter I've ever used. It featured with a 3-button stylish design, sensitive RF wireless signal receiver, and powered by 2 AAA batteries. I can literally walk around the room during the presentation without any interruption or delay on the slide show page-down/up function. You actually don't need to read the instruction, just plug in the USB receiver, open your file, and you are ready to go.

RF Wireless Laser Pointer with Page Up/down Presentation Function-Green Laser. This so far has been a great device. Bright Green Laser, only three buttons and "Laser" is clearly identified. Easy use on Mac and PC. Mac does recognize as a new device (just close those dialog windows out and you're good to go).

Satechi Storefront was great on their service and delivery. Only somewhat negative is the up button is actually down for PowerPoint. Great device for a great price.
