Well price/quality ratio
Bright and shaped line
Low power consumption Fragil glass used in the focus chamber
can´t tolerate direct impacts (i guess, i did'nt break mine to prove it) Wires are long enough to manipulate, it would be better a conector, but of course that will make the product expensive so "as is"... Read more
1. Inexpensive. 2. Lens can be replaced.
3. Lens can be rotated in a small range of angles for fine adjustment 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 ... Read more
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. I bought 2 of ... Read more
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. Non i can really think ... Read more
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. 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. I really like that this laser ...

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 ... Read more
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. 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 Wit this, a decent spirit level and a lot of carefulness you can make your ... Read more
It's small, well built module with adjustable focus and wide angle. Very bright then powered from 3x1.5v (AA, 4.5v total) batteries. 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 ... Read more
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. None really. The line has its thickness at around 0.5 mm, however for all my applications that is no issue. Very satisfied, I have ... Read more
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. 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 ...
