3 Pack Cat Laser Pointer for Cats Dogs, Laser Pointer Cat Toy for Indoor Chaser Cats Dog Pet Laser Cat Toy Laser Pointer Pen Cat Laser Light Pointer, aaa Battery Powered (Not included in the package)

I'm amazed you can buy a trio of laser pointers for this price, and get free shipping to boot. Awesome.While not cheaply made, they are a little lighter duty than other similar products. First of all, be very careful threading the enclosure together after installing batteries. Delicate, fine threads. Just it get them started and don't force things until they are engaged. The negative end of the battery goes against the laser head. The red and green are of good intensity, the blue is a little bit weak. But consider, the eye is not as sensitive to blue. It has adequate output, just a bit less than other similar models. None of them have the laser beam well aligned with the axis of the pointer housing, but the that will not affect them for pointing at things or keeping your cat entertained. If you set these on a table in perfect physical alignment and press the buttons, the resulting dots on the wall 10' away will be one to two feet apart. But, they are decent quality, work well, and are a great toy. But not suitable for kids! Buy them, put them on your desk, and fidget away.

I had an older light pointer, probably about 25 years old.... it held up well! But it finely died on me, so needed a new one for the kitties. I see some that have little pictures in the light but these are solid dots, no little pictures. I - personally - think that is best. Not sure how the others would be as bright or the dot as tight. ~ The cats seem to see the red dot best, although the others are just as bright. Maybe red is just a color cats can see better, don't know, but red is the most popular with my cats. ~ My cats are old, 16 and 12. They don't get too active about much of anything anymore. No interest in any of their toys, looking out the window, nothing~ Just sleep and are getting too fat..... because when the old pen broke, I just never got around to getting a new one for a few years. My bad. Anyway, these are a bit different. The old one was like a flashlight, push the button and it stayed on. On these, I have to hold the button down for the light to stay on. No big deal though really, but just thought I'd mention. ~ Highly recommend, your cats will love the chase ~~~

The green and violet lasers are NOT for pets and are not eye safe. But with good safety measures, these can be fun and a good source of parts for hobbyists.I do not have a laser power meter, but Torque Test Channel on YouTube measured these lasers and found the green and violet to be well over 5mW (~87mW for the green and ~43mW? for the violet). These lasers are class 3B instead of class 3R, and you should definitely not look directly into the beam unless you want eye damage. The violet might seem dim, but since human eyes are not very sensitive to this near-UV wavelength, the laser power is actually much more than you think it would be based on brightness alone. Human eyes are very sensitive to green light, so the green laser appears like it has more power than it actually does (but it is still a class 3B laser). The red laser actually might be 5mW or close (based on TTC's measurements), which makes it safer, but still, do not point it at your eyes or look into the beam.Anyways, these are actually pretty cool, and with the green laser, you can see the beam in a dark room. When doing this, it's probably best to not look at the spot on the wall for very long and to wear goggles and record video if you want to be extra cautious. The violet laser can also do some cool fluorescence tricks (probably best to aim it at something far away with no one around to minimize exposure). Keep in mind that the green laser is a DPSS laser (diode-pumped solid state), which means that it also emits invisible infrared at 1064nm and 808nm as well as green at 532nm. The infrared wavelengths are not as strong when the green is brightest, but they are still a safety risk because you can't see them and your blink reflex will not prevent eye damage (like it does with a visible Class 3R laser). The crystals that convert 808nm light to 532nm light are also very sensitive to temperature, so in the cold, the green laser may appear dim or not working. DO NOT look at the laser aperture when it's on even if you can't see light since it could be emitting infrared (likely is) that could damage your eyes. Also, do not point these lasers at the sky since that's illegal or in a legal gray area (not exactly sure as I've seem conflicting evidence) and there are serious fines for pointing lasers at planes. The green can be used for star pointing since the beam is visible in the dark, which is cool, but you have to take safety precautions that you can read about online.These are also almost definitely not built to last. I've seen other reviews that said that the violet laser and the green laser have died. The violet laser could have died because of an underengineered driver that unintentionally sends current spikes to the diode that reduce its lifetime. However, if you are a laser hobbyist and/or electronics enthusiast, this is a good source of cheap laser diodes with housings, collimating lenses, and driver circuit boards (though the violet boost driver is likely not good for anything (maybe driving LEDs)).I would recommend watching some videos and reading some articles on laser safety before using these things. Lasers can be really fun, but they can also harm your eyes. Make sure you know you are buying HANDHELD lasers and not laser POINTERS (even though these are advertised as pointers). This is more of a product for laser enthusiasts and not pet enthusiasts.

Son enjoyed disturbing the cats with the lasers. It really kept both occupied. Unfortunately my son dropped the one laser pointer and it broke. Yikes, not very durable.

First, our kitty LOVES chasing these laser lights. She now begs me to play with her using these and gets very excited when I even just pick one up. She's happy, but I'm not.You get three laser pointers with your order, which is good, but only two work worth a darn. The green one is very bright, the red one is average, but the purple one is barely visible in normal room brightness (see pic). I contacted the seller regarding the purple one thinking maybe it's defective or something. The response was, "Because the high-intensity purple beam will hurt our eyes, the faint purple will make the eyes more comfortable, safer to use, and will not damage the eyes. All purple lasers are relatively dim. I hope you can understand, thank you." I guess they don't care if the green one hurts your eyes.Another issue is I'm already having problems with the buttons. Unless you press them just right, the lasers often drop in brightness or turn off entirely. You need to press them fairly hard to keep them on. This is happening on all 3 already and I've only had them for about a week now.Overall, these lasers seem to be of poor quality and I cannot recommend them. I'll be looking around for some others to try.

Easy to use just takes two triple a batteries. Has a super sleek appearance. Safe and fun to use, unfortunately they aren't rechargeable. Though if you get rechargeable batteries, you will get more bang for your buck. Not very versatile but they function how they should.
