I use a lot of these. Repeat orders. Good quality brass housing with glass lenses. Good smooth threads. Took one apart and they’re 3 layers as advertised. Good colimating but bright halo effect around laser dot. I will switch to another lens if I can find one around same price without the halo.

Fast delivery and good packaging,
but the lens was covered in dirt and some kind of residue (polishing paste?). Had to disassemble and spend 30 minutes cleaning it.

I will give 4 stars because it seems like the lens have like a tiny air bubble in it. First i thought, maybe its just some dust or something on the lens, so i tried to clean it with some isopropyl alcohol but it did not go away. It is more towards the edge and hopefully does not affect the focusing.
But overall its okay. The shipping was fast and the item itself was well packed and protected.
