Tools and Hardware Reviews of Strait-Line 6041300CD Intersect 1/8-Inch at 15-Feet Self Leveling Crossed Line Laser
Customer Review: R Sanders
Summary: 5 Stars
I own several of the newest laser levels---the Ryobi, Straight Laser, etc. and now the Strait Line Intersect--
The intersect is by far the best of the bunch, the auto level has worked flawlessly thus far--even after a slip and fall from 8 1/2 feet up to the hard wood floor. Wish more time and thought was put into the latest tools such as this one
Oh, and by the way--it beats the pants off the other straight line laser levels offered too!!!!
THIS ONE IS TRUELY TOPS in my book
Customer Review: Strait-Line Lazer Level
Summary: 3 Stars
I found this level good for household jobs such as hanging pictures, etc. For the cost it is worthwhile.Customer Review: Useless -- not straight, not level
Summary: 1 Stars
First off, I understand the confusion some people have had with the two modes (locked and unlocked) of this product, and I understand how to use it properly; this review is not tainted by that misunderstanding. Secondly, you should understand that this product projects three laser lines simultaneously, in the shape of an upside-down "T" - one line out horizontally to each side, and one line vertically upwards. You can temporarily mount it to the wall with 3M command strips and set it to autolevel, or you can lock that mechanism so it doesn't wiggle and place it on the ground to mark straight lines for laying tile or flooring.
I purchased a new unit in factory packaging. The first thing I noticed upon firing it up is that the horizontal line was not actually straight. I set it down in locked mode on my hardwood floor (long, straight, parallel lines), and adjusted it so that one of the horizontal lines perfectly overlaid the lines of the floor. Looking down the other side, however, the beam was seriously off. I measured it as deviating by 3 inches (the width of the planks) at a distance of 82.5 inches from the source - a deviation of 2.08 degrees.
Next I put it into unlocked (autoleveling) mode and stuck it to the garage wall with a command adhesive strip and tapped it with my finger to make sure it got the chance to auto-level (and I saw it swing a little left and right and settle where it was happy). I marked out the starting point and several points along the three directions of the beam on the wall (hence doing this in the garage). Then I took a normal four foot bubble level (something like this although a significantly cheaper basic version) and marked out level points to the left, right, and vertical above the intersection point. I marked arbitrary crosses on each of those level lines and measured their distance back to the main intersection, and the deviation to the laser line at that distance. On the right, the beam was low by 13/32" at 46 + 15/32" out from the intersection. On the vertical, it was left of level by 7/16" at 47". And on the left, it was low by a whopping 1 + 1/4" at 45 + 29/32". (Yes, it was low on both the right and the left sides, since those two lines are off from each other by 2 degrees as mentioned above.) If you extrapolate those deviations out to 15 feet (where the manufacturer advertises it should be accurate within 1/8 of an inch), the error I observed would grow to 1.6 inches, 1.7 inches, and 4.9 inches respectively. That's an atrocious 13 to 40 times worse than the advertised accuracy.
If you do a little more math, you'll see that the vertical line is at least very close to being centered against the horizontal lines - each angle that should be 90 degrees is almost exactly 91 degrees instead. Then on top of that problem, the autolevel tilts about half a degree to the left.
Even if you only wanted to use this device in locked mode to lay tile or flooring, it wouldn't be very useful because the angles are off. Combined with the apparently miscalibrated autolevel, it's almost completely useless (unless you want to shoot a straight line in one direction).
Since lots of other people appear to love it, perhaps I just have a defective unit. I've contacted the marketplace seller, and if they choose to send me another unit I will update this review after checking it out.
UPDATE:
The marketplace seller preferred to refund my purchase rather than replace the defective item. I may buy another instance of this device, but don't hold your breath for another review update.
Customer Review: Very useful for simple projects
Summary: 3 Stars
Seeing this for a good price from Amazon.com, I thought they'd be extremely useful for DIY work and ordered two of these -- one for myself and one as a present. This device uses a laser passed through a lens to project a "cross" onto a surface. The horizontal line was very bright and showed up well as far as 20 feet away (just as advertised), unfortunately, the vertical line was so faint that you could only see it in very dark rooms (e.g. no ambient lighting from windows) or when the device was within 1 foot from the wall. It took us a while to realize that the device must be mounted directly to the wall you are hanging the pictures on (using sticky adhesive provided in the box) to be able to use the laser lines. It will not work if you want to put it elsewhere in the room and project the lines onto the surface of interest. That said, it is extremely useful for aligning pictures and other items on the wall; however, if there's a door frame or other raised feature on the wall, the beam will not project past this feature so this limits the usefulness of the device.Customer Review: Works for what it was designed for.

I have used STRAIT-LINE 6041300CD Intersect Laser Level to hange pictures and set up some shelving in my basement. It worked. No complaints.
