Rated 4.0 out of 5.0 by BobC Laser level tool...
Bosch Laser level, GPL5S. (SKU 1000010441) from Home Depot. This product was supplied by Home Depot through the SEEDs evaluation program.
The Laser level is about 4.0 inches long, and about 1.6 inch wide, and 3.0 inch high. The level with batteries weights about 8.8 oz. (Without the adapter base attached) The laser level is powered by three AA batteries, comes with a carrying case that will fasten to a belt for carrying. There is also a mounting base that screws onto the base of the Laser level. The mounting base is a adapter, that has magnets, and slots for a mounting strap. This adapter can be used to attach the level to different surfaces for setting up a reference beams. They also supply a target plate for in spotting any of the five beams. The Laser level projects five beams, covering three planes, X,Y, and Z. There is a slide switch that turns on the laser, as well as locks the beam mirror optics from moving when in the off position. On the bottom side there is a threaded hole for a 1/4-20 screw, so that the level can be used with a standard camera tripod. The laser level is designed to be “self-leveling”, that is the five beams are projected from a reflector assembly that is suspended inside the laser housing like a pendulum. The Bosch laser level carries a two year Warranty.
The level is designed to be used as a reference for construction projects. When installing walls and partitions, or any object that needs to be level, square to another object, or perpendicular to floor plane. I have used these levels for installing cabinets, and shelves, and for aligning pictures on a wall.
The user manual goes into detail about how to check the calibration of the level, and how to adjust it if needed. I haven’t seen this type of detail in other product manuals, nice of Bosch to include this information. I did run a quick check of the calibration based on the information in the manual, and found this unit to be calibrated right on. The level seems to perform quite well. The only thing that I found amiss, was the adapter base that comes with the laser level. The one I received was not flat on the bottom, so if it was attached to the laser level, and placed on a flat surface, the whole level would “wobble” like a chair with one leg too short. Investigating this, revealed that the adapter was constructed of two plastic halves, that when assembled, they did not line up flush on the bottom and top sides. This produced a offset at one end of the assembly.
The “bottom” of the laser level assembly without the adapter attached was fine.
Observations; The easiest way to make use of these type of levels is to use them with a tripod. There are 1/4-20 threaded mounting holes in both the level assembly, and the adapter attachment, which attaches to the base of the laser with a 1/4-20 screw. In use, the laser beam spot does diverge as the distance from the level increases. At about 35 feet I noted a beam spot size of about 1/2 inch. If projected out to a 100 feet this would probably be about 1.5 inches. I would have liked to have seen a smaller beam spot, no more than 1/2 at 100 feet. In cases like this, you would have to estimate the center of the beam for your measurements. The manual spec’s the maximum calibration deviation to be 9/16” at 78 feet from the laser. So, if your beam spot is as large at the calibration limits, there is some question as to what the real accuracy is. In actual use, I would suggest that the center of the spot would be the most accurate to measure to. Better collimation of the laser beam would help.
As with any alignment laser tool, when used under brightly lit conditions the laser beam, or spot is very hard to see. To aid with using this this level under these conditions a target plate is included with the level. The target plate has magnets to allow it to be placed on steel framing studs or other metallic locations. This would be handy in aligning metal stud partitions. There is also a strap that is included to be used with the adapter base, so that the laser could be mounted on odd shaped objects, such as pipes, or wood posts.
Except for the two items I noted above, the laser level seems to perform quite well. I hope this information is helpful.

Rated 5.0 out of 5.0 by Melissa Our favorite level
We love this laser level. We have used it to build 3 rooms in our house at this point. It self-levels and provides three full axis of laser lines to mark against. It is very solid and well built. We highly recommend investing in this level - you will not be disappointed.

This is a great tool. I used it to keep my fence strait and true. I placed it on the corner so I could get two angles at once. It worked great. I also used it for the grade. A very nice tool. I wish I would have had it when I framed out the new room. It would be great for that application. Very well built and easy to use. They are being used on most of the construction sites I'm working on for framing and running pipe.

Rated 4.0 out of 5.0 by Jim1234 Excellent tool!
Previous reviewer is right, the beams are not the brightest you can find. I have seen a bunch of different point lasers over the years and there are some out there that will give you a better laser dot for sure. But they're still plenty bright and I love this one because it's so small I can carry it with me at all times and that to me matters more. I also like the fact that it locks when you switch it off, they say it will help it keep its accuracy over time. All in all an excellent tool, I have used point lasers for a while, saves me from doing all those 3-4-5.

Bought the gpl5 to use for framing out windows and doors on welded metal buildings, on the very first use I noticed the laser was off in only 3 ft. Last building I checked it, the plumb laser was off almost a 1/2" in 16 ft. Shouldn't have to try and recalibrate it new out of the box. Very hard to see laser dot outside, even on a cloudy day.

I keep my Bosch - GPL5 with me all times. Im not only a regular construction employee. Also once we finish build we also help our costumers hanging ther pictures or design plates on dinning room master wall. Easy to carry on my backpack is with me 24/7. Also it is easy readable out doors at the time to level the ground on a manhattan townhouse backyard.

Rated 1.0 out of 5.0 by contractor Not durable for construction
I've bought two so far and won't buy another. The first one was dropped ten feet and feel apart and we couldn't get it back together. The second one. The small battery clip slid into another clip and shorted the unit out and won't come back on. In done with these. The last laser I had was a Stanley and I had it for over ten years. Looking for a new durable laser.
