Digital Electronic Level and Angle Gauge, Angle Finder with Bubble Level and Magnetic Base, High Contrast Display for All Environment, Measuring Tool for Carpentry, Building, Automobile, Masonry

Bought this for green reading of slopes for golf and works great. Excellent tool to train the eye to read slope and to judge required lines for putting. Will be useful for home uses, as designed, too but I purchased for golf use.

This little guy has been an excellent addition to my toolkit. As a college student, I found this tool incredibly helpful for one of my projects, where precise measurements were a must. The device is battery-powered, which makes it convenient to use, and it performs exceptionally well. I have had no issues with it so far, and its accuracy and reliability are top notch. I would recommend this product to anyone in need of a dependable angle gauge, whether for professional or academic purposes!

Got this Digital Electronic Gauge & used it occasionally over 60+ days. Yesterday morning I used it to set my jointer fence but when I tried to use it about an hour later to set my saw fence it wouldn't turn on. Replaced the batteries but still wouldn't work. Checked the battery voltage & both sets were well within usable range. Sent a message to the vendor but since it's been over 30 days I doubt I'll even get a reply. I ordered a Klein gauge today to see if it lasts any longer. Handy tool but the market seems to be flooded with cheap junk, so buyer beware.EDIT: The seller did contact me and ultimately replaced the gauge, so they do stand behind this product! Changed the rating from 1 star to 4, one off for the gauge failing.

Good Product

Easy to understand and use. I use this electronic level to set the level of my antique clocks. Price was very competitive.

I've only used it once so far. Easy to zero in. Comes in handy for small areas.

I needed to determine the grade of my model railroad track inclines & declines. Once. All I really wanted to know was that they were around 3.5 degrees.The Digital Electronic Level and Angle Gauge, Angle Finder with Bubble Level met my requirement well and is now sitting in my cabinet waiting for me to think of what else to use it for. I'd much rather have a $20 device sitting in my cabinet than a $50 device.

This is the second of such devices I have owned. The first being a Wixey that suffered a catastrophic failure when dropped onto a concrete floor. Simply, a surface mounted choke coil broke away from the PCB. Yeah, it could be fixed, but would never get me a nice, illuminated display like this device has.Out-of-the-box, added fresh batteries, turned it on and zeroed it on my kitchen island counter, waited a few minutes for the electronics to warm up to ensure there was no zero drift (there was not) and turned the unit 90 degrees onto its right side. Display measured 90.00 degrees to my satisfaction. turned the unit back to its original zero point, and the device displayed 0.00 degree to my satisfaction. Turned the unit 90 degrees onto its left side, and a disappointing 89.55 degrees was displayed.Okay, maybe my aim was a bit off and it was taking into account a bit of front-to-back ramping of my counter tops. So, off to the shop with the ground surfaces...Set the device on a ground granite slab and zeroed it out. placed a 1-2-3 block known to be accurate next to the device, ensuring the granite surface was free of any debris. Turned the device counter-clockwise and allowed the magnets to adhere to the 1-2-3- block and got a satisfactory 90.00 degrees reading. Set the device upright on the granite slab and it returned to 0.00. Moved the 1-2-3 block to the other side of the device and rotated it 180 degrees to ensure I was registering against the same side as the previous test, rotated the device 90 degrees clockwise and allowed the magnets to adhere to the 1-2-3 block, and again, got a reading of 89.55 degrees. So, as long as I measure in a counter-clockwise orientation from zero, I should be good. That works for my right-tilt saw. But, not ideal looking at it from a general use perspective.Unlike some other devices of this type, the measurement surfaces are plastic and subject to the inaccuracies of injection-molding techniques. There is a slight bow to each measurement surface which could influence the measurement if you applied pressure to one extreme or the other or even the device being at a steep angle and the weight of the device shifting its reference angle a bit.Following the instructions in the manual on how to manually calibrate the device, I used the corner of my cast iron table saw bed as a reference point. Calibrated it 10 times, each to the same conclusion, rotating the device around its vertical axis, 180 degrees, resulted in an offset of 0.45 degrees. I did not find any way in the manual to manually account for this offset. Surprisingly though, it did improve the clockwise\counterclockwise accuracy from zero - they are both exactly 0.05 degrees off (89.95). So, as this is the designed use for this device - measuring relative angles from a designated zero point - and the offset is within the specified tolerances, I guess it has passed. But the fact that it cannot maintain a zero-reference when rotated around its vertical axis leaves a bad taste in my mouth. After all, this is the basic way we calibrate ultra-high precision levels that cost hundreds of dollars more than this one.
