The actual output power of this laser is about 7000mW. The cooling system is very good, and it does not generate much heat even if it works continuously for one minute.

The 555nm laser is pretty unique. The laser spot is bright even during the day. I love the USB charging feature; it's super convenient, as I can charge it using my laptop or a power bank. The 10mW output isn't very high, but it's more than enough for me.

I've powered these diodes with 4.2v batteries. They were really powerful and stable.

The actual power is close to 4W (> 3800mW), and the heat dissipation is also good. However, its battery life is not as good as I expected.

This is a powerful and compact laser pen. I recommend choosing the 450nm version, as it is more cost-effective.

This laser pointer exceeded my expectations in both performance and quality. The build quality is excellent. It feels sturdy and well-made.

I tried using this dual-color laser in a bar. The green and red colors were beautiful together. One of my friends loved it and asked me where I bought it.

This is the first time I have seen such a special laser pointer. It is not only multi-color but also very powerful.

I've used this thing while diving. Even at over ten meters underwater, the laser output was super stable and it kept running for a few minutes without any water getting in!

The green laser is powerful and bright. Don't accidentally turn it on while looking at it.

It is exactly what you want from a green laser pointer. The laser beam is strong. The attachment is quite cool, featuring various patterns.

I didn't know what laser was suitable for me before I bought it. The customer service rep, Lucy, was very patient and explained the principle of light thoroughly! Thank you so much.

It has plenty of power to point out stars in the night sky, and the battery life is long. Love this thing!

I purchased the 7W version but received the 5W version! Then I replaced it. However, it wasted a lot of my time!

Overall, this laser pointer works well for me, but it has no O-rings, so please be careful where it is wet or dirty.

I recently received this green laser pointer! The laser beam is long-distance and perfect for stargazing in dark areas. I've wanted one of these for a long time, and I'm thrilled with my purchase.

The product manual is not very detailed, and some users who are not familiar with lasers may encounter difficulties in operating it.

I wear these every time I use a CO2 laser cutter. They're fully certified, which gives me peace of mind about safety.

I highly recommend this store to anyone looking to purchase a laser module. This veteran-owned company always goes the extra mile for their customers.

For the price/performance ratio, this laser is well worth buying. I chose the dot version. It may not be scientific research grade, but it's suitable for most daily applications.

After placing the order, I waited three weeks to receive the product. The aluminum box was damaged during shipping.
