Review: Nice and bright. Also, you can focus the beam. - These little guys are pretty decent laser diodes! They’re super bright and fairly inexpensive. I used three in a project for an ECE class at UCON and am very happy with the results. While I think they have a resistor built into the driver I’m driving them at about 4.5V with a 100Ω resistor in series with the device. The small package was easy to integrate into my project enclosure. I noticed that these are focusable. You can twist the collar near the output side to focus the dot. Yes, laser diodes don’t have a perfectly round dot, but when focused properly, you really can’t tell by eye over short distances. At 100 meters, you will definitely notice dispersion and distortion, but I very much expected that. All in all, these met my expectations, and I’m happy with how things turned out. They work great. Note: I only have a few hours of use on my project, so I can’t say how long they will last, but like most things electrical, you can pass a low amount of current through them for a long time or a very large amount of current through them for a very short time. If run at spec, I assume they will last just fine. BTW, I got an A on my laser transmitter project. W!
Review: 10 Pieces for a great price. Easy to work with, and for my needs they seem perfect. - The price for this 10-piece set was fantastic, and the delivery was faster than I expected. I have not powered them all on yet, but I took a random sampling of 4 and they looked bright and uniform. The spot-size looked uniform in an 'across the room' test, so the laser quality seems fine. For my application, the "precision" of the aiming is done by hand, so I also wasn't too concerned if they are/not perfect in that regard. The lead wires would be a concern in an environment that experience much of any vibration, but that too was not a worry for my need, so I think they will be more than sufficiently durable. The size, of 5 mm diameter was easy to work with, and since I was 3D printing the holder, I could adapt to most anything. I also appreciated the option of either 3.3V or 5V, the latter of which was right for this project, but I also work with 3.3V designs, so I'll keep that in mind for the future.

### ⭐⭐⭐⭐ Work Ok but a few stopped working
*by K***V on July 20, 2025*

These are Ok red lasers, but not for mission-critical projects. Some just die without warning, and you will need to replace them. I had a project with 32 lasers, two died before I installed them and 3rd one died later. But they are cheap and when they work - they work.
