James ★★★★★

I hooked this up to my Arduino and the beam stayed perfectly focused at about 10 feet, which was great for my light-sensor experiment. The 5V input worked exactly as described without any flickering.

Jacob L. ★★★★★

The little beam is surprisingly crisp for such a cheap module, and it threw a clean red dot across my whole workbench. Took maybe five minutes to wire into a 5V supply and it’s been steady since.

John R. ★★★★★

Hooked it up to my Arduino and got a bright red dot on the wall from across the room. The beam is surprisingly sharp and focused for such a tiny module.
