  • Perfect for DIY projects. Cheap price and works as expected.

    Involvement Level: Expert (understands the inner workings)

    Pros: The price is very cheap and the product works as expected. Is perfect for your DIY projects. You can use them to make a prototype and then go for a higher quality (and more expensive) larsers.

    Cons: The beam quality is not excellent, but is enough for the price that costs.

    Other: Very easy to use. Just a positive (red) and negative (black) wires. You only need 3V to get it working, so, you can use two simple AAA batteries, for instance.

    posted by qsxdr1 on 18:16:54 G4T 12/04/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The lasers are very cheap, pretty bright (especially for the price), focusable, very small, well focused right out of the box, Focus can be changed with a screwdriver

    Cons: Not great build quality. I have had to re solder the connectors a couple times on a couple of them. Not very bright and cant make a red spot in brightly lit areas.

    Other: Very good for the money but if you can afford it, buy extra laser modules especially if you do not know how to solder.

  • Strong beams, but somewhat fragile units

    posted by vilarcamaraneto on 22:13:34 G12T 17/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I expected a small unit, but these are tiny! The beam is stronger than I expected.

    Cons: One of them came defective (does not turn on). Filed a ticket about that, let's see DX's response. Aside of that, the product seems very fragile and should be handled with care.

    Other: Perhaps you should expect the bad luck of receiving a defective unit? Another user reported a weak beam, I have a non-working one. If you really need four units, either buy two of these or search for a 5-pack.

  • Great for non-precise laser tagging

    Involvement Level: Expert (understands the inner workings)

    Pros: The price is very good and it has the expected quality, you can hook it up in seconds and start pointing wherever you want. If you want, you can create your custom laser, and put it inside anything you want.

    Cons: The adjustment is not very clear, but for the price it is good.

    Other: They have the best quality-price

  • Very good toy

    posted by allangood on 06:13:16 G9T 03/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a very tiny and easy to use and easy to embedded laser module. It works with 3.3v (Arduino). The price is very good, almost $1 for module. The light is very bright with nice (for the price) focus.

    Cons: The wire is very weak and need to be handled with care. This is the only bad thing, but is expected because the tiny size.

    Other: It's a good deal. Nice price and nice quality. The time to arrive to Brazil surprised me, only 2 weeks.

  • 4 red laser modules

    posted by iyorgova on 04:18:08 G5T 23/05/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 1. The price: under 5 bucks for 4 modules
    2. VERY tiny thus easy to embed almost anywhere
    3. Good focus out of the box, easy to fine-tune with a screw driver
    4. Powerful enough to be visible in direct sunlight at at least 10 meters distance
    5. Only need 3 V to light up and very powerful with 3x1.5 V button type batteries even of the smallest size

    Cons: 1. They come in a 4-pack but one of the modules would not perform well (only reaching 1/5 of the output capacity of the other 3, regardless of the voltage supplied)
    2. One of the modules was missing a wire
    3. One of the modules' PCB was kind of unaligned (but still performing well)

    Other: They work perfectly, at least 75% of them! ;)
    These modules safely manage up to 4.5 V button type battery power (as in electronic wrist watches) and they did not drain the batteries for more than an hour of work. This is an achievement bearing in mind the very limited capacity of those tyny buttons ;). Standard AAA batteries would last for ages.
    A perfect miniature module, an excellent buy!

    Involvement Level: Expert (understands the inner workings)

    Pros: -Gives a nice laser light -Works good with 3V button battery (SKU.34714) -The four arrive working

    Cons: -The cables soldered to the terminal are very weak, one even got out while using it.

    Other: If you'r carefull or you know how to solder terminals, you should definetely Buy this, its a good price for 4 lasers, and the best its that you can decide where and how to use it!

    posted by jakoab on 08:00:04 G11T 14/11/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I think it is a very good red lazer module for a prise like that, because it works very vell. And all the lazer modules lighted weary well. And it is easy to use when you can somthing about electronic.

    Cons: Bad information about the lazer modules, they are plased under the green lazer Category. It is not good enuf to make a red point when it is very light outside. And the lazer modules had long delivery time, I got it afther three weeks.

    Other: Very good price, all of the lazers worked very vell and they are easy to use. Because the long delivery time makes me give it four points instead five points.
