I tend to put a lot of effort into trying to get shelves, pictures, and other household projects to be level, so I use laser levels quite a bit. This Bosch unit is nice in that it has a nice clear beam even in daylight. It is also a step up from cheaper units I've used in that it projects a cross pattern for aligning both in vertical and horizontal axes. For example, I mounted a column of shelves on the left side of a wall and wanted another column on the right side. Very easy with this level as I could adjust the vertical line to where I wanted the shelves to be on the right and then I adjusted the cross-hair from a horizontal aspect to line up with the shelves on the left. Easy.

You'll likely find that using a tripod is the easiest way to mount this unit for use, though it does come with a handy clip attachment if there is something stationary nearby that it can be mounted to. The clip can be easily removed when not needed.

There does seem to be one flaw however. When the device is within 4 degrees of level it uses an internal pendulum to auto-level itself, which is great. Most of the time this is the way to use it. When it is rotated more than 4 degrees, the beam stays on so that you can self-align for more diagonal oriented angles. Again, nice. However if you want to self-align with the laser but want to use it still within 4 degrees of level, there is no way to disengage the auto-leveling feature and just leave the laser on. There are times when I want to use the laser for a straight/perpendicular line but don't necessarily want it to be level with the horizon. There doesn't seem to be a way other than being at an angle greater than 4 degrees. It seems like it would have been easy to disengage the pendulum (which happens when you shut off the laser anyway) but leave the laser on for use.

Not something I thought of before I purchased it. Maybe those more handy than me would find this to be obvious or maybe suggest this isn't the right tool for this kind of job but I'm just an amateur when it comes to home projects and spending quite a bit more for a level than I had to, I see this as a downside of using the item.

I'm very pleased with this item! I wanted a way to make sure my craft projects were straight and this works wonders. I also love that it comes with an attachment where I can fasten it to the table I'm working on. I also have a tripod that works to hold it for hanging pictures etc. Would definitely recommend to a friend!

Purchased this laser line level to paint custom lines in one of our bedrooms, worked perfectly. I only wish there was an option to stop it from flashing when the unit is not level, not every line in the world needs to be level.

Used this a few times already and seems like the laser turns on and off here and there. Seems like there is some kind of short. Other than that it works and the laser is pretty bright during the day.

It only gets 4 stars because the first one was broken on arrival (the on button would not stay in the on position, even if I held it in place the laser would not turn on). Amazon provided a replacement and the second one works as advertised. I read previous reviews where people complain about the laser blinking. This happened to me too at first. I noticed that as I shifted the unit angle around, the laser stopped blinking and stayed constant. I am assuming the unit has to be angled just right for a true level and if it is not, the laser blinks to let you know. I'm happy with the purchase.
