YILAYMEI Portable Torches Super Bright Beam Flashlight USB Rechargeable Charger for Astronomy Hunting

In my quest for something uniquely captivating for my cat's playtime, I stumbled upon an extraordinary gadget: the Green Laser Pen. This device is far from your typical cat toy. It's a powerful tool originally designed for astronomy enthusiasts, capable of projecting a brilliant green beam that can reach far into the night sky. However, in my home, it serves a more down-to-earth purpose: keeping my feline friend utterly mesmerized.The Green Laser Pen's standout feature is undoubtedly its intensity. This isn't just any laser pointer; it's equipped with a beam that commands attention, whether used under the stars or across the living room floor. The brightness and reach of the laser are impressive, making it perfect for pointing out celestial bodies or creating an irresistible target for cats. But with great power comes great responsibility. The laser's strength is such that it requires careful handling, especially around pets. Ensuring the beam never directly hits my cat's eyes is a top priority, as safety always comes first in our play sessions.Another significant advantage of this laser pen is its rechargeable nature, thanks to the included USB charger. It's convenient and eco-friendly, eliminating the need for constant battery replacements. The portability of the laser pen also means it's easy to carry, whether I'm heading outdoors for a bit of amateur astronomy or simply moving from room to room, engaging my cat in a lively chase.

Great product. Very satisfied.

It was what it said it was. A nice laser but damn this thing is powerfull, so powerfull that my friend was convinced it wasn’t legal. Buy with caution! But aside from that it was a very good product and is quite well made for the price (:

I love this laser. Unbelievably strong - get it before someone takes it down for being too strong. I bought one for me and for my brother who lives 2 miles away with clear sight between us we can signal one another no problem. Now I'm getting a 3rd one for some experimentation. Also, it doesn't appear to overheat as many of these devices do - I accidentally put it in my trouser pocket whilst it was on, perhaps 5 minutes elapsed before I realised it was on - took it out and had barely any heat build up. Great quality all around except perhaps the "pattern" cap which can be a pain to get on/off.Battery life is refreshingly good and it charges in no time.

Seems well built extremely bright would probably blind the cat

Very strong, and impressive distancing between A and B. Impressive for the price however once assembled cannot be contained in the box. The screw in part is a bit fidgety so wear and tear is inevitable without concentrated lite use of oil.Not to be used on or near animals, not to be used on or around children or adults the beam has a high intensity flare, it could cause temp/perm blindness. Just looking at point Bs beam from distance A around 6feet can indeed be dangerous. Do not look directly at lens once it's on as that too can cause perm blindness/ headaches, nausea, migraines etc.....Would advise if you want to use a laser to play with animals get a lesser intensity version.

I am very impressed to own this amazingly bright laser. I can confirm what another revier said, that the light from this laser lights up a whole room. It seems to work OK - though the manufacturer says don't have the laser on for more than 30 sec at a time else it will wear out faster. The end of the tube/battery lid needs to be carefully screwed on I found and likewise the diffraction grating attachment on the front - if you choose to use this. Really useful for pointing out things in the sky for astrononomy or for teaching science in education. BUT I'm wondering, why is there no power rating for this laser? Even more worryingly why no warning yellow triangular stickers on the device its self? There really ought to be an age limit restriction for customers buying this device to avoid it falling into the hands of children or teenagers as anything over 5mw can cause permanent eye damage if used close range. We just don't know the power rating of this device as its not given. Also the seller needs to include warnings on not to point it at people, vehicles or aircraft at a distance, as it may blind temporarily or distract. When using lasers beware of reflections from the surfaces of shiny objects as these can in effect dump a stray beam into ones eyes, or the eyes of pets - so be very careful when using this device indoors. Maybe even think about buying laser proof googles which filter out much of the green light.

This is the most intense laser ever built, and its beams are helping me probe the fabric of the Universe and into my neighbors window.Inside my research lab in my shed, bright green light fills the vacuum chamber of a technological behemoth. It is the size of two tennis courts. The walls are shielded with 60cm (24in) of concrete to stop radiation leakage, and the my wife and I wear masks and hairnets to ensure the delicate electronics are not affected by our filthy selves.This is Trevor, soon to be the most powerful laser in the universe – and now it is whirring into life for its first official experiments.Unlike the continuous lasers that scan your barcodes in shops,Trevor is a pulsed laser, firing in bursts a few quintillionths of a second long. Each pulse will be capable of reaching a peak power of three petawatts – equivalent to a thousand times the electricity consumption of the whole world. A laser capable of such extremely compressed energy will help researchers to study the quantum laws underpinning reality, for example, or recreate the conditions of extreme astrophysics out there in space.We’re so pleased that the battery life had improved and that it functions in a functionally controlled manner.
