It's very compact and lightweight - ADE Advanced Optics HB06-1 Triple Duty Blue/Violet Laser Sight w/ Picatinny Mount

I purchased the blue laser, and it's very compact and lightweight. Seems to be very strong and durable though. It has a lot of good features for its size. The functions are easily accessible and easy to use. I love the fact that the charger is magnetic, how convenient! The beam is very crisp, too.
Now for the negatives: The radius of the beam is very small, and I had a hard time being able to track it during the day. I tested it in my driveway and side yard. The only time I could see the laser dot was when I aimed it inside a dark tent, maybe at most 15 ft away, or the beam was hitting an object about five feet in front of me, and even then it was hard to see. It's definitely more visible at night, however, I question the visibility distance at night that's claimed. Much like how my daylight visibility test didn't hold up to what's claimed.
The visibility may be perfectly within the expectations of hunters, as I wouldn't know because I don't hunt, I just like to play lol. But I was rather disappointed. Features and perks are great, but it was the laser I was wanting. And for me, it was left wanting.
