I have allowed myself to be convinced by the positive reviews on this laser pointer. It was delivered quickly accustomed. As extra batteries for the laser pointer part of the product, it could go even equal.
The laser pointer is good in my (large) hand. It is rugged processed (aluminum) and makes a high-quality optical impression. I now use it intensively for 5 days. The battery power I can not (yet) judge. The AAA batteries should however hold for a while. My cat is the new toy very pleased. The laser projects a sharp, red dot. The range appears to be high. Although I though only use the laser in the apartment, the point is also well projected on the house wall in approximately 75 m distance.
As only drawback I find the button to activate the laser. Although the switch also appears to be robust. Who wants to be turned on the laser beam, but may not take the switch finger. For presentations that may indeed be pleasant and sufficient in continuous use when recording of cats it is after a few minutes of constant pressing but exhausting. In my case, Puss is then but already KO, so this limitation does not fall further consequence.
Overall, I can recommend but the laser pointer for sale without restriction.
