this thing is amazing. get a tripod if you don't have one.
honestly, wow. won't ever go back to bubble levels again.i used it to hang curtains near the ceiling. at first, i pulled it out of the box and thought to myself "how do i get this high enough?". initially i tried sticking it to my ladder, but it didn't go high enough for the horizontal laser to line up. then i realized you can freaking tilt this thing and it will auto-level. so you can have it a few feet below the object you're trying to level, aim it, and it will produce lines up near the ceiling. pulled out my bubble level to compare and it was always dead-on. crazy.but really, it's best with a tripod. i have a Smallrig RA-S280, about $60, which i already had lying around and this Bosch uses standard 1/4" tripod thread so it worked. being able to height adjust with the tripod made it far more reliable as if the mounting surface is even slightly wobbly, the laser will be unreliable. i also love the magnetic mount option for added flexibility where a tripod might not fit.

Solid laser
Works great when you don’t feel like holding a level. You’ll need a decent tripod. I’ve used the expensive commercial laser levels and I would say this is a few steps below the higher end bosch models. Great for around the house/ light duty use. Well worth the price.

def buy on sale, one of the best low tier lasers.
one of the best, on sale it’s a steal. use 3 of these for i installing or fabricating and it makes your job easier. all the good lasers are expensive. this one is obviously not as precise and as well made but i’ll buy these when they go on sale. take care of them and your laser alignment should be good for a long time. the magnet is good and useful. red lasers oc not as visible as the greens but in a shop setting it works great

Satisfactory Unit, Bad Mount
The level seems good, made of heavy plastic and rubber moldings. The laser is bright indoors and accurate enough for my needs. The manual mode however is not what I expected. I thought that there was a manual switch where it locks the laser and the unit can be tilted any which way. But the only way manual mode can be achieved is by tilting the unit sideways until the laser unit rests on the walls within. Only then can the laser can be tilted to your liking. The laser will then blink intermittently for seemingly 2 purposes: to tell you that the laser is not level and that you are in manual mode. The blinking interval could be shortened, but it's not a big deal.The big deal is the mount that comes with it. From the pictures, it looks like there are two types of mounts. The one I received have large knobs. The main picture on the amazon site has the small knobs. Anyway, the 2 ball heads within the arm section of the clamp still slip and slide and cannot support the level no matter how hard I tighten the arm knob. I have a tripod that I can use but I need the mount for a particular work.If the manufacturer can chime in, I'd appreciate it: I would like to know if this is a defect that is unique to my unit and if it is, how do I get a better mount without returning the entire package to Amazon?

Did what I wanted it to do
This is my first laser level, so take my opinion for what it's worth.This did what I needed it to do - assist in installing a shower. I didn't have much luck with the included base, (not sure what it's supposed to clamp on to!) but I was able to use my own tripods of various sizes to get the lines I needed. It does need to be dialed in level so it doesn't blink, but I would guess that's the same with every laser level. The red laser worked fine for me indoors. Never tried it outdoors.

Simple and easy operation. Obvious when it isn’t level unlike some brands and their esoteric operations and controls. Great price. Literally can’t beat it.
