UNI-T Digital Angle Finder Magnetic Angle Cube Gauge LM320B, Rechargeable Digital Inclinometer Laser Level box, Woodworking Measurement Tool with LCD and Backlight

I normally use bubble levels but you generally can only measure 0, 45 and 90 degrees, nothing in between. Also trying to get a bubble exactly in the middle is nearly impossible. Basically a bubble level is usually just "good enough". The accuracy of this angle gauge is almost too accurate! I almost wish it had a setting to change the decimal to 10ths or even whole degrees from 100ths. Not a complaint though, this thing rocks. But because of its small size and footprint it is vulnerable to small variations at the location where you are measuring. If you want real accuracy I would suggest getting a steel rule 12-36" long and sticking the angle gauge to that.It makes it easy to measure non-standard or unknown angles. It has strong magnets on both sides, the bottom and the back. I wasn't sure what the back magnet would be good for since it doesn't measure angles front to back but it comes with a steel plate that has a hole in the corner. I suppose you could attach that by a nail or screw on a wall, stick the angle gauge to it and then line up pictures, trim, etc using one or both of the lasers.It has 4 different units and most likely the one used most will be the degrees setting. It also has mm/m and in/ft which would be very helpful for measuring roof rise angles and maybe stair rise too. Finally it has a percent unit setting and I have no idea how to use that but it appears that 0 and 90 degrees are 0 percent while the halfway point (45 degrees) is 100 percent.There was also included in the box a clear plastic disc that has like a gel or sticky side. The Amazon listing states it is a "viscose" and there is no mention of it in the instructions. I have no idea what that is to be used for, maybe to stick to glass so that the laser shows up better?

The battery don't last longer that 3 days and after a 2 months can no longer be charged. Device was hardly used to the the terrible battery life and is not useful at all as it doesn't switch on

I’m an electrician and this one does not have a strong magnet either. It won’t stick to the pipe and it rolls around or slides off. No bueno. The Klein one seems to be the only one with a strong magnet and a groove for the pipes.

This is a very versatile device that I am happy to have in my toolbox. It is a quick and easy way to measure any sloping surface. Just turn it on and place it on the surface. It is very precise. In fact, if you are trying to level something, the accuracy is such that it is difficult to exactly hit 0 degrees. The screen is bright with large digits and it is easy to read. When the level is at 0 degrees a blue line appears, then when off-level a symbol appears near the top of the screen that indicates which direction away from 0 degrees it sits. It charges using a USB-C cable and there is a battery-shaped charge indicator on the screen showing its status. The unit is well built and feels nice you your hand. The rubber edges are great and they stop the device from sliding around. The instructions are okay. In total, this is a great instrument and a good value.

The media could not be loaded.  +- 1° even after calibration. When flipping it, readings should be 0-90-0-90

UNI-T Digital Angle Finder Magnetic Angle Meter-InclinometerThis inclinometer works very well and it is fast in obtaining your angle reading. It measures angles to 0.01 of an inch. The meter is very sturdy and should last year in use. The built-in magnet works great for attaching to a metallic surface and not moving!!! It is very accurate (I compared to a standard bubble level). It works great for leveling your framed certificates or photo. The rubberized surfaces help to keep the meter from sliding on the surface that you are measuring. The display is big, bright and easy to see. It is about the size of a standard construction tape measure (25 ft). The USB-C charging is a plus – no batteries to change. I would recommend this inclinometer for home and construction use.

If you need exact (1/100th of a degree) display of a surface’s angle, this thing is great. I go nuts trying to get something dead-on with a bubble/spirit level, and this thing lets you take that even further.The lasers are selectable (either on, both on, or off) and allow for laying things out based on the angle of a surface or component.Nice pocket sized measuring tool! Based on my experience with other items from this brand it should be a good durable tool.
