Huepar Digital Angle Gauge Protractor, Electronic Bubble Angle Finder Dual Axis Level Box 0.01° Resolution V-Groove Magnetic Base&LCD Inclinometer Bevel Gauge with Audible Alert -Measures 0~360° AG03

This is really a great tool, appears to be very precise, easy to use, the magnet is fairly strong. It comes with a nice instruction manual in several languages, I think the English section was about 17 pages, well written and covers all the use cases. Note you may need your reading glasses, it's pretty small print. That being said, it's very intuitive and easy to use without having read the manual. I have used similar, though not as good, manual and digital devices in the past. I commonly use them for setting up telescopes and around the shop for getting blades perpendicular to the surface of saws. The precision and capabilities of this tool really blows away anything I have used before. I would highly recommend this, even if it is slightly more expensive than some of its competitors, you won't be sorry.

Works great. Easy to use, my only complaint is it doesn't hold the most extreme angle, which isn't thaf big of a deal. Magnet on bottom is nice. Battery life seems to be good so far. Well worth it for the process point.

I don't have any similar device or experience to compare with, but this digital angle finder seems to work as advertised. The buttons to operate are a little small, and the readout is a little awkward to see, but I'm working around those annoyances. I'd buy it again. (Wish it had magnets on all edges and a more pronounced cylinder groove)

Great product, seems accurate 👌

This is a review both for the product and support. I work in medical device manufacturing and use this level for simple things such as installing shelving and leveling desks. The ag03 did a great job at both of these things, although the processor and screen refresh rate could be a little bit faster. In some cases, the reduced processing power can also lower battery usage, and the two AA batteries have not run out of juice yet. Fair for how much they are charging and gets the job done. Pretty close to the end of the warranty period my LCD screen stopped working. There wasn't any physical damage and I was watching the device while it lost the picture on the LCD screen (it still powers on and off, but does not display an image). I've seen this happen with some of the device LCD screens I work with. I contacted Huepar and not only did they promptly respond in decent English, but they also stood behind their product and replaced it for me with no hassle. It was a very Costco like experience. I think it's always worth noting when a foreign company stands behind their product since I've also had many negative ones. Four out of five for the device and five out of five for the customer service. Going to round it up since I am so impressed.
