improves focus & beam divergence over distance

Used on my zeus-X, this delivers better beam quality with improved focusability both near and far. Highly recommended accessory.

Don’t even question it. It’s a must.

If you have a high power doide laser. Then don’t even think sbout tryjng to get away with not buying this. I tried and I then found out how useful it is in every aspect. From expanding the beam to further the distance into the sky, to close range burning to it allowing you to burn things across your yard. I mainly use it for in the sky and to point things out. It allows me to turn my blob into a pretty sharp dot at 330 meters. Also, this is a good price. I have seen these expanders in this same style and power sell for $60

Geese Freak!

I have a green 50mW laser that will scare geese off the pond at twilight or at night but is useless during the day. With the Zeus Combat laser the geese freak out instantly and can be used 24/7. Recently I visisted a friend who has a 16 acre private lake. He has a big problem with geese (noise & poo). There was about 35 geese on the lake and they were all airborn within 2 seconds after I turned the laser on. I think my friend will be ordering his soon.

You guys deserve it all

Hi, my name is Alice. I don’t usually write reviews, but I felt this experience was worth sharing. When I reached out to Zeus Support, they took the time to help me and explained my options thoughtfully and professionally.

I’ve looked around at similar products elsewhere, but nothing seemed as trustworthy or authentic. What stood out to me is how Zeus Lasers treats its customers. They truly listen and make you feel genuinely valued, which is so rare these days.

Even though I’m new to their site, I’m already excited about all the advanced tech they offer, and I believe it can help me and my loved ones. I can’t wait to see what else they have in store next! As a scientist and science teacher, being able to experiment and discover new ways to grow with technology like this is incredibly rewarding and I owe that to this company.

Thank you, Zeus Lasers!❤️

It works!

I got good results on my arm within one month (had pain for more than 3 years after a basketball game without proper warm-up). Pain is now gone. Good lasting battery and the quality of the device is decent!

As good as it gets for yellow

Yellow lasers are expensive and inefficient compared to green, blue, red, purple, because there are no natural emitters in that frequency range.

The beam is generated by two separate lasers emitting in the IR which are combined to basically double the frequency. You won’t get the intensity or the 10’s of Kilometers of reach of the greens and blues. The intensity of this laser compares to about a 10-12 mw 532 nm laser.

But if you need a yellow laser, and it is beautiful, this laser is the only game in town and reasonably priced.

It is also in a safe power range to use as a pointer when presenting on a large screen and looks very impressive.

Pain relief

I started using this laser for lumbal pain relief and the muscles of the lower back (Gluteal muscles). In fact there`s muscle relaxation and pain relief after 3 minutes. Best results by treating the area in a distance of 2 inches (~5cm). I am excited.
There a good contact to the company and a good support!

The geese are gone! they HATE this laser!!

I bought mine at the end of 2024. I live in a condo on a brook leading to a river on Lake Erie. I have lived here for 5yrs. We have had hundreds of geese descend on our property and do what geese do, and that is make noise and leave a mess! I have tried everything. Very bright flashlight, drones, grape kool-aide, fake predators etc. Nothing worked! It was extremely frustrating! I continued researching until I found an article that said geese don't like green lasers. It was worth a try. So, this 550mw laser was cheaper than a drone and more expensive than a flashlight. I bought it. I tried it. The geese HATE it! They fly away instantly from even 300-500ft away. I started hitting them early this season and they have not returned for about a month. Even those with little goslings, who won't fly, turn around go away as fast as they can. Make sure you get at least 550mw and I don't think you will be disappointed. This thing is very powerful! It will even burn things at close distance. I'm sold. Geese no more! Goose poop gone! It's worth every penny.

This laser device has impressed me with its power and apparent effectiveness in pain management and recovery.
I have been using it consistently for about 15-20 minutes each evening for three weeks, I've experienced a noticeable reduction in my pain levels and increased flexibility.
The device is easy to operate, and the included safety glasses are a must-have. Additionally, the included massage lens is a useful addition, providing an option for gentle massage alongside the laser therapy.

I've been dealing with persistent shoulder pain for months and was looking for a non-invasive treatment option. After researching cold laser therapy, I decided to invest in this laser device and I'm incredibly impressed.
The build quality feels solid right out of the box. I appreciate having the two different laser applicators – the smaller pen-style one is perfect for targeting specific trigger points, while the larger head covers broader areas like my shoulder joint effectively. The digital display and controls are intuitive and easy to use, making it simple to set the treatment time.
Most importantly, the results have been fantastic. After using it consistently for a few weeks following the recommended guidelines, I've experienced a noticeable reduction in pain and stiffness. My range of motion has improved significantly. Highly recommended for anyone seeking an effective at home laser solution for pain management!

Professional LLLT Powerful Cold Laser Therapy Low Level Healing Device 955mW For Body Pain Relief

Professional LLLT Powerful Cold Laser Therapy Low Level Healing Device 955mW For Body Pain Relief

This laser has all the hallmarks of high quality design.
The beam is strong and bright.
The body is all metal.
It has a button that you press once, and the laser stays on continuously until you press it again, allowing you to place it somewhere and let it work on its own for a few minutes.
It comes with a charger, box, and a good quality Japanese battery.
I definitely recommend it if you are looking for a good laser kit for under $50.

My oldest dog has IVDD due to a neck injury and I bought this device. It's very easy to use it and it's compact. My dog does lay still through the treatments and I truly believe they make a difference in his healing.
Very glad I bought this instead of paying vet to do it.

Das Gerät macht einen sehr soliden Eindruck und auch der Händler ist top! Als ich nach einer deutschen Anleitung fragte, wurde sie mir innerhalb von nur 1 Stunde zugesendet, super Service!
Das Gerät ist nun im Dauereinsatz. Es kam sicher verpackt an und die mitgelieferte Aufbewahrungstasche ist auch sehr praktisch. Diesen Händler kann ich wärmstens empfehlen.

WOW

Perfect service. Arrived on time, Great communication, Fast response to questions.
Laser EXTREMELY bright. incredible power and range especially with expander. Measured power 1.93 watts so very close to advertised (my beam power meter is relatively cheap with stated -/+ 3% accuracy) spec. Finally, the mode button may seem like it's not working in terms of high / low power but after testing it does work it's just imperceptible especially with goggles.

Overall definitely recommended this laser!
