Economical Red Dot Laser Module, 650nm, Class 3R, Less Than 2.5mW, with APC Driver, 2.6~6V Operation Voltage, D7xL21mm, VLM-650-03 LPA, Laser Head, Made in Taiwan

Worked perfectly for what I needed

Perfect laser

the wires were too hard to put on, and I couldn't get them on

While it works fine, it does not display a dot it’s a really short line. Functions fine for what I need but not what I was expecting.

It does what I need it to do. Tested with 3 AA batteries in series (still designing the pcb for the final project for this) and saw that it shines as I would expect a laser to do. Wasn't a perfect circle dot as others have mentioned, but it's close enough for my needs.

It worked very well. Nice crisp dot and then all of a sudden the entire module came sliding out of its housing while it was mounted. I tried to place it back in but now it’s not centered. It wasn’t exposed to any extreme heat. It’s unfortunate because it’s a really nice laser for the money.

This laser LED is surprisingly bright, considering the low power consumption. Very pleased.

I replaced a burned-out laser guide in my chop saw (Porter Cable/Delta 3802L). Fairly easy replacement. This laser is bright and focused. The saw's power supply worked great - very little messing around with wiring was required. The original laser ($105 to replace !!) gave a line, this replacement laser is only a point of light, but it falls exactly where you need it - where you want to cut.
