    I’ve had the Robotoolz > porter·cable 5-point laser that this tool is based on for 8 years or so. It finally died after 7-8 years of abuse.

    The model/s this is based on used to ‘lock’ the laser once it was done auto-leveling. This new mini-me model does not. This shouldn’t be a huge problem but i’m taking off a star because of it simply because with my old unit, it would NOT wobble around when walking near it and this one is in constant pendulum mode so will wobble/wiggle with any microscopic vibration.

    FYI: there is no ‘magic’ to the ‘auto leveling’ it doesn’t use servo motors etc; it’s simply a pendulum :-D on the higher-end models where you can hear a pulse like a motor doing adjustments, it’s simply a mechanism that releases then grabs then releases then grabs the pendulum so when it’s done the pendulum is locked in place and you don’t get a wobbling laser dot.

    There are some good points brought up in one of the low-star reviews that are valid and stooped on bosch’s part for having some gross errors in the manual:

    1. it would seem that there is no longer a ‘mode’ for calibration; it is *always* in calibration mode. I owned the older model that this device is based on; it had a pendulum ‘grabber’ that would ‘tick tick tick’ while it was bobbing around and when it was happy that it was done, it would hold the laser beams solid so you wouldn’t get the bobbing and wobbling as you walked around on the floor near the device. IGNORE the step how to get into and out of calibration mode and i’m quite sure it will work as described in the manual.

    2. the ‘ tripod mount is built into the multi-purpose attachment. this is the same as the older brother to this device as well.

    3. it’s true that because the laser goes through a few prisms in the path out of the device (it’s a very smart design because it make sure that the five beams will always be perfectly normal to each other), the dot will a) have diffraction interference dots and b) will get larger the farther away you are.

    with respect to 3, the center dot will get pretty big at distance, but it will a) have a CENTER and b) have smaller and smaller dots going away from the center; example the center dot might be ¾ inch diameter but the 6th interference dot left or right of center will be only ‘ ” diameter. You can get a very decent level from the horizontal offset dots and you can get a very decent plum from the vertical offset dots. it’s not perfect but it works perfectly well.

    i’ve used the older brother to this device for 8 years (finally died after using it literally in a puddle of cement), and i will miss the locking feature that the ‘calibration’ function was made for, also since the ‘overthrow’ function of the power button (you would push PAST on), to engage calibration mode, was also used to defeat the auto power down function, i’m not sure if that’s possible on this model and that will suck.

    It would be FAIR to rate a THREE based on the sloppiness in the manual not ‘getting’ that there is no longer a calibration mode but that you CAN in-fact still CALIBRATE the friggin’ thing, you just need to get past the bug in the manual, but i think dropping the fancy wobble grabber will likely make this model more reliable long-term.

    You can also defeat the auto-off (20 min) function by turning the unit on then off then back on immediately.. it will blink fast for 2 seconds to confirm the auto-off was ‘disabled’ (quotes because it will shut off after 8 hours!).

    From a ‘construction’ standpoint I would be dead-in-the-water; i pretty much literally use the 5-point laser for every single thing i build; it’s fantastic for putting in garage doors (4-5 i’ve done), entry doors (about half a dozen), kitchen cabinets (dozens in several kitchens), tile floors; many; the square function is priceless.

    you can use the strap to strap onto a 2×4 and with this new model, it has 2 holes in the removable base to SCREW to a wall, then project a dot onto the NEXT stud and use as a reference to drill a hole; you can get a PERFECTLY horizontal set of holes for beautiful results when putting in wiring, or you can use a pitch offset (drill each hole ‘ inch lower than the previous and get a perfect ¼” per foot slope!)

    There is NO other way to make sure counter top (cabinets below) are at the same height than using this type of tool. It’s also priceless for getting doors perfectly plumb; you can get things to 1/32″ over 8′ really easy, that’s not so easy with even a 4′ level.

    in a word: INDISPENSABLE

    I’ve been using this laser on and off for about 3 months. I’ve had no major concerns with it as I simply use it as a reference point. There are more expensive/precise lasers out there, but this one does the job just fine for me.

    I do think the tripod mount underneath is a little awkward, but since I usually just set it on the ground it is of no concern for me.
