BOSCH GTL3 65 Ft Wall & Floor Covering Laser, Includes 4 AA Batteries, Versatile Steel Positioning Plate, Laser Target, & Pouch

I used it for the first time last week while doing a 400+ sq ft tile job here on Long Island in NY.At first I thought thought the laser light wasn't strong enough but after playing with it for a few minutes right on the tiles I found it to be quite sufficient light wise.I marked some layout lines with my chalk line and square to see how close the tool came to them and I have to say it was within a 1/8-+" of my lines. I'm guessing that it was my lines that may have been off but even splitting that I'd have to say it's real accurate.The room I was doing was about 13'x31'.Another nice thing is the laser line jumps right over my spacers which I used sticking up from the tiles rather than set into the tiles..and the line falls back onto the edges of each tile.I HIGHLY recommend the Bosch GTL3. If I had to do it all over again I'd buy it in a heartbeat.

I bought this for a bathroom floor tile installation. It did not help me much on the walls. Laying out the wall tile I used my levels. It does have a really nice plate for mounting it to the wall. For larger rooms it would probably be more useful or if I was putting the tiles in at an angle. For the shower I was doing not so much. For laying out floor tile this laser is really nice. Most walls are not perfectly square. This laser will save some time in that you can move it around until you get what you want. It is a lot easier to move around than a big lay out square or drywall square. You can measure of one wall and snap a line. That is what I used to do. The problem is when the walls are not square and your trying to fudge a little here and a little there. The diagonal line is also nice. It was very handy and It helped me set up my floor plan. A friend used it for tiling a laundry room and has ordered his own after using mine. I only gave it four stars because I thought the line was a little light. I expected a brighter light. The line shoots down and creates a nice square right in front of the laser. I am happy with the product and look forward to using it again on my next project.

I bought a competitor's $59 laser and was very disappointed with laser brightness and beam width. I then ordered the GTL3. Excellent brightness and beam width. Xcellent functional design. Excellent tool with excellent value. Pricey but worth it.

This tool has been an absolute lifesaver for me, as a DIY enthusiast with limited tile work experience, who was looking for an alternative to replacing the carpet in my basement. It helped me maintain proper alignment throughout the entire process, and I highly recommend it to others looking to take on similar projects. Although it may be a bit pricey, it has already proven its durability, as it kept aligned and bright even after I accidentally dropped my saw horse table on it.

I finally broke down and go this for the tile job in my house. With almost 2,500 square feet of tile to lay, this looked to be the easy way to get my lines straight. It's pretty much pop the batteries in and push the button. First use was to layout the tile down a hall that had about 1/4 total clearance with full tile widths on the width, and this made it a breeze. I've used string lines and chalk lines, string gets in the way and does not stay tight or straight when you start hitting it and chalk lines get covered up. I was shooting down over 30' with clear laser lines on the floor all the way, made setting tile a breeze, especially since I am using rapid-set thin-set for the first run (isle that I need to walk on before tomorrow). If I was using any other method, I'd be stuck mixing small batches and setting 2-3 tiles at a time, I could run with full buckets with this.Only issue I ran into is very minor, the time-out is a little on the short side, I think it's about 45 minutes and it shuts off. I like that as it will save on the batteries, but unless you reset it after every bucket of thin-set, it will shut off on you.I have also used this for laying out for framing walls and it works really well for that too. I almost forgot I had it when I was laying out 3 rooms and this made life a lot easier. This will pretty much made any straight line/45/90 degree layout job easy, whether it be tile, framing or whatever else you are doing.

While this in theory is a good tool to have. I have successfully used it to lay tile and keep a straight line, but it's much more difficult to use than one might thing. I tried watching some videos online. May be expensive for what it offers vs just snapping chalk lines - but I do like that I don't get chalk on my hands and all over the place.

I've been a tile contractor for more than thirty years and have been using laser tools since they first came out. Back then you could pay thousands of dollars for a spinning line laser. I have used Dewalt ,Rubi, Straightline, other bosch's, etc. and this one is the best. I kinda balked at the price because now you can get good laser's for about half of what this sells for if you watch sales. Now that I have this one I wish I would have got it years ago. The line is crisp ,narrow but consistent and bright and best of all it has a 45 degree feature. the design allows you to have the tool behind the lines you are checking/creating. Some lasers sit right on the line wihich makes it harder to use when you have already set the tile and are checking them for square. After a new purchase I always double check my laser squares to make sure they are precise and this one is the most accurate I've ever had and it seems to be solidly built. I even use it for single lines because unlike most lasers this one is the same thickness from the start all the way to thirty feet out and more. I'm getting one for all my tile setters. If you've never used a laser square this one pays for itself in one or two jobs.
