A dimmer switch is for sure nice to have. I was thinking about to add it too. But I didn't want to spend so much for the first laserpointer. You know, sometimes you are excited about something you want to buy, choose the best version you can get and after a short time you don't use it alot.Those are immense lol, they look durable as hell though. I was tempted to go with a laser ranger for the dimmer switch.
So I added some gadgets to play around a bit... like lasersaber attachment, star caps and a line lens because that wasn't so expensive.
