Hello, so I recently purchased the $55 445nm 1 Watt laser from o-like. I've purchased from them before, and I trust them. Anyway, everything was all fine and dandy when I received the laser. Shortly after, I noticed that when I spun the focus back to its "original" position (where it should be a straight beam), it was not focused and had a large dot. In order to get a straight beam, I have to manually focus otherwise to achieve that. I don't know what happened or how to fix it. I would like it to return to a straight beam when I spin back the focus the entire way. I know this was worded poorly, but hopefully you guys can catch my drift. Let me know if you have any questions.
