    This review is about maximum distance: 40 m, number of required batteries: 2

    I haven't used it outdoors for more than 5 minutes, even with clouds, and that was with great difficulty. Indoors, it's fine, I haven't encountered any issues. Generally, the batteries drain quickly. For example, in measurements of 5 hours, during which I turned it on and off, a pair of batteries drained. It's okay for its price. I didn't expect anything extreme.

    I got it to have a second auxiliary laser. It is not suitable for outdoor use at all. Its laser is very weak and cannot be seen in an outdoor space, not even in shade when it is more than ten meters away. It works fine for indoor use.

    This review is about maximum distance: 60 m, case: No

    Very useful tool, I saved a lot of time. I have been using it for 1 month. It has millimeter accuracy, its screen is black with large white numbers and symbols. Under sunlight, the screen appears faint, the laser is not visible when aiming at a point, so you are not sure what you are measuring. The laser is visible with effort at 10 meters in cloudy weather.

    This review is about the maximum distance: 100 m

    Very user-friendly for indoor measurements only. It measures area, volume, angles, and triangle sides. It has a bubble level, but also an electronic one which is equally accurate, as mentioned in other reviews.
    In no case is it suitable for outdoor use with sunlight, maybe up to 5-10m. If it has strong sunlight, not even that.
    It also displays results in ft and inches.
    Honest for its price, but 4 stars as it does not cover outdoor use.

    This review is about the maximum distance: 100 m

    Very user-friendly with many options for measuring square, cubic, rectangular triangles, etc. It performs additions and subtractions on the measurements we give it and saves the results. It also has a level (both physical and electronic). With the summer sun, it will be difficult to see the laser beam during midday hours. A protective bag is included.

    I haven't used it outdoors for more than 5 minutes, even with clouds, and that was with great difficulty. Indoors, it's fine, I haven't encountered any issues. Generally, the batteries drain quickly. For example, in measurements of 5 hours, during which I turned it on and off, a pair of batteries drained. It's okay for its price. I didn't expect anything extreme.

    I got it to have a second auxiliary laser. It is not suitable for outdoor use at all. Its laser is very weak and cannot be seen in an outdoor space, not even in shade when it is more than ten meters away. It works fine for indoor use.

    Indoors, it is perfect and expensive and user-friendly. When it comes out in the sun, things become difficult.

    It is user-friendly and reliable. I haven't used it much yet nor have I read the manual for the additional features. It works very well in the basic functions. I am satisfied. I would recommend it.

    Very useful tool, I saved a lot of time. I have been using it for 1 month. It has millimeter accuracy, its screen is black with large white numbers and symbols. Under sunlight, the screen appears faint, the laser is not visible when aiming at a point, so you are not sure what you are measuring. The laser is visible with effort at 10 meters in cloudy weather.
