    • Very good performance
This little powerhouse gives you that extra kick needed, with a pwm module it is very tunable, has an awesomely tight focal point, and even at 100% power stays relatively cool and the forward air flow through the heatsink/body pushes smoke away quite easily, for less than $60 I doubt you're going to find better, at least in a DPSS laser module. I've wandered between 5mw up to 50000mw over 40 years of laser experience, and an important thing to know is that the laser, although I have not officially tested it, is kicking out the 4, 000mw it claims, and might even be a little closer to 5 or 6,000mw, it's power output from my experience tells me you're getting exactly what they advertise, and perhaps a bit more. I consider it an excellent purchase, but with one caveat, this needs to be run with a pwm module, if not, you can wire it directly to your power supply, (Whether that be a 12 volt plug in adapter or a regulated power supply) no harm will come to the laser from this type of hookup. This is perfect for the laser enthusiast who does not intend to engrave with it and wants to hook it up directly to a 12 volt DC power source, I suggest using one that is rated at 3 amps or better. One final thought, if you wish to connect it directly to a DC power supply you must also connect the pwm module lead, (yellow) to the positive, (red) lead to get it to function, just remember if you do this it runs at 100% power all the time, but won't hurt the module. To simplify, you will have to cut off the connector of your power supply, and one end of the three lead red-black-yellow connector cable and solder those two together cables together, so basically you have a black to black connection, a red to Red connection, with the yellow lead also connected to the red to red connection. Simply plug in the connector to the laser module, then plug in the adapter, I suggest using shrink tubing on all solder connections. Watch out though, at 100% power even if highly unfocused at 3 to 5 ft will cause painful burning on your skin within seconds. ... show more

    • Great... While it lasted
I had this sitting around for a few months and finally got around to hooking it up a few weeks ago. Initially it worked great, no issues with engraving at all, was very impressed with it. But after using it intermittently for about 2 weeks, the laser no longer fires. I can hear the fan running so the unit is getting power, but cannot get any output from the laser any longer UPDATE: LASERTREE contacted me shortly after this review and sent a new control board, which sadly did not solve the problem. However I notified them of this and they happily sent a new module, which does indeed work great again. Bumping the review back up for the excellent customer service ... show more

    • Works great and lots of power for the price. Only focus to a point, no beam.
One thing people should know is that if your just buying it to have a powerful laser to play with it doesn't focus the beam in a way that will stay culminated (did I kill that poor word). Thats to say it won't make a tight beam it will only focus a point within about a foot of the laser and then it widens so you'll need another lens to get a beam out of it. But if your using it the way its intended it should work great. ... show more

    • This thing can engrave rocks and uncoated steel easily
And it doesn't even need to be perfectly focused unless you want a really tight spot, since the relatively long focal length means the cone that the beam forms is fairly acute and it cuts pretty well even when 10-15mm away from focus (so it absolutely WILL engrave your buildplate if it gets through, but can be used on odd-shaped items like random rocks you can find in a garden or slices of a tree cut off with a chainsaw). Careful not to set your house on fire or not to get free eye removal surgery, as it is surprisingly powerful. It's not like you can cut out something like an engine gasket with it, unless you have a lot of free time and want it to look ugly. It would need to be even more powerful than that. ... show more

    • Just Like the Other Reviews, Disappoining Performance and then DEAD
Big promises very little performance, I di not get a chance to try it until just a few days ago so the return widow is now closed which is unfortunate because this unit is weak and controllable it is terrible no wonder the price was so low! VERY disappointed again from another hyped up but poor delivering product from Amazon and the chinese sellers. Why don't you try a little honesty? if your product is JUNK tell it like it is instead of inflating your own egos and the true specifications of the product and stealing from hard working people trying to use your products that never seem to work and if they do work at all, not very well and if the do work a described, for how long? Try making a better product that can actually be used... ... show more

    • Great small 4 watt laser but does not use a std m9 -.5 thread
Review Image by Joe
This is a great little laser, 35X35 mm, but it delivers every bit of 4 watts of optical power. Hard to beat for this price. It can easily burn pine at 500 mm/ min with 35% power. It can cut thourgh chip board (like a cereal box) at 100 mm/ min. I have not tried to cut plywood, but it should be able to handle 1/8 inch at 100 m,/min full power. It is defintately not strong enough to engrave on any raw metel. I have tried aluminum and ss. no impact even at 20mm/min and 100% power. One negative is that the lens barrel is 10 mm instead of the standard M9 .5pitch. Even though you can change the focal length (by turning the lens), I could not get it to focus under 24 mm. The lense can be removed, but it is an odd size. It appears to be an m10 .5 pitch threads. ... show more

    • Reliable and Easy to Adapt
This performs exceptionally well! The four tapped holes on the back make mounting super convenient. My Genmitsu CNC mount wouldn't fit the laser, so I just drilled two diagonal holes in the carriage of my machine to meet the holes on the laser module. While the wiring wasn’t arranged correctly for my machine, it was an easy fix using tweezers to adjust the JST connection. After approximately 20 hours of use, I haven’t encountered a single issue. This is a reliable and well-designed laser module for engraving and cutting projects! ... show more

    • perfect laser for my needs.
Make sure it works with your system which it does with mine. Works better than the original. I would order it again should I need another one.
