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

I purchased this red dot laser module and so far it works very well. The size is compact and easy to install, exactly as described. The red dot is clear and visible, even in well-lit environments. The material feels solid and the performance is stable. It’s a great option if you’re looking for a simple, functional laser at a good price. I recommend it for small projects or basic use.

Worked perfectly for what I needed

I had to send this back because it is very misleading. It doesn’t work without having to get some other kind of piece to connect it to and it comes to zero instructions.

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.

Perfect laser

Excelente producto me funcionó ala perfección la conexión fue fácil lo recomiendo

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.

小型で軽いレーザーポインターが必要になり コチラの商品を購入させてさせて頂きました。 安価で品質も良く満足です。

These work very well with arduino laser sensors.

All I wanted was to have sharks with frickin' laser beams attached to their heads! Let me just tell you, it’s impossible! First off, this laser was too small for the intended purpose. Not all of them are weapons grade. Second, the shark was totally uncooperative and unpredictable. Do yourself a favor and research, research, research if you hope to avoid complete disappointment.

Firstly the laser isn’t centred so when you fit this or do what ever you are using it for the dot won’t be aligned up. After many hours of lots of minor adjustments to the fitting I got it as best as possible. Great.... happy days :) I thought until 3 weeks later when the laser went dim and after about another week it died completely. Battery replaced and connections checked but no sadly the laser was confirmed dead. Shame Amazon doesn't vet it’s sellers / items more closely as like this there is a lot of items not worth even considering.

作動電圧１．５Vとありますが良くわからず、３ｖで光りました・
