Отзыв о USB Rechargeable Hyperlink Wireless Presentation Clicker Remote Control RF 2.4GHz For Keynote/Mac/PC/Laptop - DinoFire Green Light от Jim Ledbetter

The laser is okay. If you are looking for something that you click on for a second or two every couple minutes, this should work fine for you. If you are a heavy laser user, you should avoid this one. The casing is plastic which makes it difficult for the laser to dissipate heat and it will go dim after a minute or so of constant use. If you let it cool down, the laser will come back, but it's a bit annoying if you are teaching with diagrams.The other issue I have with this is that the laser comes on momentarily when you plug in the charger. Make sure you aren't looking into the end and that it isn't being pointed at a shiny surface/people.I can't speak too much for the remote control aspect. I got this model mostly because finding affordable green laser pointers is rather difficult at this moment.
