  • Works as expected

    Pros: 1. Inexpensive. 2. Lens can be replaced. 3. Lens can be rotated in a small range of angles for fine adjustment

    Cons: 1. Line quality (intensity and shape) varies a lot along the line. I wanted a thin line at the distance of 200mm. However at both ends line is dashed. 2. The laser spot without the lens has an elongated shape 3. When rotating the lens quality of the line changes, due to the shape of the laser spot

    Other: Good quality for the value!

    Pros: Get this laser if you're looking for an entertainment-grade device (eg. a laser for a smoke machine light show or a toy weapon targeting system). For precision measurement and alignment either get a professional cross-laser from a home hardware manufacturer, or a pair of line lasers that you'll be able to line up and calibrate manually.

    Cons: I bought 2 of these and both had slightly misaligned prisms, meaning the lines weren't 100% perpendicular and their length was different.

    Other: ooookkkkkkk

    Pros: When unpacking, I was really surprised by the mechanical buld quality. The module itself (the cylinder) is made from stainless steel, only the lens holder is made from plastic, but also covered with stainless steel. We use 4 of them to mark the corners of the female mould while producing fiber reinforced plastic: works great.

    Cons: Non i can really think of... but wait, yes, there is a small one (not really worth mentioning): On the label glued on the barrel, there the ratings are not marked :)

  • The best choice for cheap laser scanner solution!

    posted by dimetikon on 05:13:17 G2T 08/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The laser is focusable, so you can adjust the line to about 1mm thickness or even less, and the line is bright enough even when powered from 3.7 li-ion battery.

    Cons: When focusing the line you must rotate the hole laser around lens :( otherwise the line rotates too. It is really not good for using in static laserscanner devices.

    Other: I am fully satisfied with this product and use it for DAVID laserscanner successfully. This is really good option for starter kit.

    posted by kappe9000 on 13:43:23 G9T 04/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very good quality and bright laser line. You can focuse the line by turning the front of the laser. I use it for a laserscanner and it works perfectly. The laser line is about 2mm at is thinnest at about 5cm from an object. I put in 5v and this works fine, but i am sure this will decrease the life of the unit, but it fits my project better and makes the unit a little brighter. I have also tested it a 3.5v and still the brightness is good.

    Cons: I have no bad things to say about the product.

    Other: I would recommend this product to everyone looking for a line laser.

  • Much better than what I thought

    posted by lpanagis on 10:40:32 G8T 23/08/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Pretty good, relatively small and light operates just fine from 3V to 5V. Beam strong enough to be visible at least 10 feet away on white walls.

    Cons: Beam rotates as you focus it. Be very careful to glue or otherwise immobilize the focus ring or your beam is not going to be level

    Other: I am planning buy a few more for a 3D obstacle avoidance module for a robot. Stay tuned!

  • nice thing

    posted by Stinkynnov on 07:11:43 G7T 17/07/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It's small, well built module with adjustable focus and wide angle. Very bright then powered from 3x1.5v (AA, 4.5v total) batteries.

    Cons: As noted in other reviews, line ends are blurred and looks like a series of dots. I don't think it's really a con - it's visible only at the very end of the line. Other moment - module label shows several options for shape and power supply but there is no marks which of then are suitable for this module.

    Other: Nice, cheap, and works.

    posted by bb990 on 08:14:30 G11T 08/11/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a small, well built unit - easy to mount it anywhere; the line is focusable - about two turns of the lens covers the whole focus interval, very even along the length - only tips of the light are slightly uneven.

    Cons: None really. The line has its thickness at around 0.5 mm, however for all my applications that is no issue.

    Other: Great product for the price.

  • line is fine

    posted by emnemn on 13:41:54 G3T 04/03/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Makes a nice line, works well. easy adjustment stabel line. needs no refocussing when it is on for a hour. very nice thin line with equal brightness. Its small. Bought 3, all were fine, and gave the same line. Can be focused.

    Cons: Its not a perfect line. The middle looks great, but both ends look a little bit like a line of dots. Its only the last 5% of the line, so for most purposes it will be fine

    Other: if you need a small cheap laser to make a red line don't look further, you found a good one! well worth the money..

  • Able to focus but at the expense of other features

    posted by bestenemy on 20:55:08 G2T 02/02/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Able to focus the line. Can work with higher voltages compared to all other 5mW red line lasers at Deal Extreme.

    Cons: Line starts breaking up at the edges. As a result, the intensity of the light is uneven. The line achieves sharp focus when the focal ring is almost at the end of its thread, quite often you'll end up popping the tip off unintentionally. The prism turns with the focal ring, meaning your line will turn also when you're focusing. The head is a bit loose - will wobble.

    Other: If you're looking for an entertainment application laser - get this one. If your project requires precision - a solid line that doesn't wobble when the laser is under mechanical stress, then go for a 2~5mW 650nm Line Laser Module.
