Customer Questions & Answers

Is the magnet strong enough to adhere to metal studs through dry wall?

Asked by: Anonymous
The magnetic base on the GLL2-40 is not typically strong enough to hold through drywall (depending on the thickness of the drywall used) It would hold on perhaps ¼” drywall but not ¾’’. However you can purchase the WM1 wall mount that has stronger magnets on its base/back and also a screw hole for attaching the mount to the wall.

30 ft. Cross Line Laser Level is rated 3.7 out of 5 by 11.
Rated 2 out of 5 by from Does not stay on longer than 10 min. It does not last longer than ten minutes in operation. I need it to stay on until battery life runs out or i turn it off.

Rated 2 out of 5 by from bad magnetic mounting base it is a sturdy design i know that because it is constantly falling when i used the magnetic mounting base but after the impact has finally taken its tole it still levels but gets stuck out of level some times due to the constant falling i dont use the magnetic base anymore not impressed good level but cheap magnet has ruined it

Rated 5 out of 5 by from Perfect tool for my line of work. As an automotive lift inspector, I feel this tool is a must have item.

Rated 2 out of 5 by from The magnets are terrible... I bought this laser because I usually love Bosch tools. This one, right out of the box was so annoyed. The magnets are the worst. It only sticks to strictly metal. Not on the wall like the Dewalt one does, but I obviously did not want to buy Dewalt when I could get Bosch.  But now I'm almost hoping I did. I'll see if I can fabricate a fix for this. Wish it would work out of the box. I'm sorry Bosch but you really let me down on this one.

Rated 5 out of 5 by from Very handy I needed a solution for keeping the grout lines straight on a long backsplash job. Under the cabinets, tight space, no way to mark the wall. The GLL2-40 was the perfect answer and more than paid for itself in the time and frustration it saved me. Job turned out well and I now carry this gizmo with me whenever I'm checking out projects. Very handy to know - and be able to show customers - what's plumb and level, and what's not.

Rated 5 out of 5 by from Easy to use I brought this level to help me get get porch railings level around a gazebo and 90 degree porch. Mounted the level on a camera tripod, raised it to the desired height, rotated the level, and easily marked all the posts for the same height. It is really great that this level is self leveling and I didn't have to try and get it leveled before using it.

Rated 4 out of 5 by from simple as it can be. I got this laser and could not wait to use it. Performed the accuracy check as instructed and was ready to go. The laser worked great (used it for a new kitchen cabinet install), very bright beam, it leveled quickly, toggling from horizontal to vertical, etc was intuitive... really dont need instructions. It is very simple to use. Now for the bad... 1) the soft case is not very useful and I'm not sure how this would protect it from bumps and dings. Instead, I used a hard case from a Bosch router, cut out the unecessary webbing and installed some foam and its much better... it fits a small camera tripod also. this is what should come with it. 2) For some reason, it did not turn on second day. It had power as indicated by the toggle button on the top but the laser did not light up. To Bosch's credit, I sent it in and was replaced with a new one within a week of sending it out. GREAT CUSTOMER SERVICE.

Rated 4 out of 5 by from Good product I have only had it for a month. Used it for putting up 3" x 6" backsplash tiles in the kitchen.  It worked great, nice to have both vertical and horizonal lines.  The only thing that I did like is that it turns itself off in just 30 minutes.
