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

I love this laser. Unbelievably strong - get it before someone takes it down for being too strong. Doesn't overheat - 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.

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.

The box it came in was cracked and rubbish hence the 4 stars and not 5. The device it's self is crazy powerful and super bright. This is definitely not a cat and dog lazer pen. Yes it's £16 but it's well worth every penny in beam length and brightness

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.

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.

Amazingly bright light that does just what I wanted. It did need charging before the first use but it didn’t take too long.

Absolute rubbish, It didn't work, I fully charged the battery & it still didn't work, returned for refund.

As in an avid bird feeder/watcher, I feed all types of birds, but the mean old magpies swoop down and chase off all other birds, especially small songbirds. I’ve tried everything - from tinfoil and wind chimes, to simply clapping my hands loudly to scare away the magpies. Nothing has worked. So I bought this as a last ditch effort to keep the magpies out of my garden.Enter this laser pen. It’s actually scary how powerful this thing is!! It’s safe to say the magpies absolutely hate it! Literally no magpies are in my garden now, for fear of this mighty green laser. Very pleased with this solution.I’d highly advise using this thing with extreme caution. It’s immensely powerful, you can see the dot very clearly even in bright daytime, through a double-glazed window. The length it reaches is crazy. Hitting rooftops across the street in broad daylight. Insane!It’s way too strong to use as a toy for my cats. Even looking at the dot on the ground hurts my eyes. If it were to accidentally hit a pets/persons eyes, it would likely cause some serious vision damage. Definitely must be used responsibly. For those looking to get it as a cat toy, I’d say buy a different one as this is simply too powerful and will damage your pets eyes.Amazing product though. I’m surprised it’s being sold legally on Amazon to be honest, without even an age restriction for delivery. This thing is not for children/teens!
