Wonderful pocket tool!
This is an extremely handy thing to have and it works great! Built well and seems to be very accurate. I love that I can bring this for projects instead of my big level. The price is great for what it does.

Accurate Angle Gauge – Perfect for Knife Sharpening
The Klein Tools 935DAG Digital Electronic Level and Angle Gauge has been an excellent tool for precision work. I primarily use it with my knife sharpener to make sure I’m getting the exact angle on my blades, and it’s made a noticeable difference in consistency and sharpness.The digital readout is clear and easy to read, and it quickly measures both 0–90° and 0–180° ranges with accuracy. The magnetic base makes it easy to attach securely, and the compact size means it doesn’t get in the way while sharpening.✅ Pros:Accurate digital readout for precise anglesMeasures 0–90° and 0–180° rangesMagnetic base for secure placementCompact and easy to handleGreat for sharpening, woodworking, or general leveling tasks❌ Cons:The small display might be harder to read in low lightRequires batteries (included, but be sure to keep spares)💡 Tips:Place it on your knife sharpener’s guide to ensure perfect sharpening angles.Store it in a safe spot to avoid dropping, as precise tools can be sensitive.Works great for other uses too — like setting angles on saw blades or woodworking tools.Always calibrate before use to ensure maximum accuracy.Bottom Line:The Klein Tools 935DAG is a versatile, precise, and reliable angle gauge. It has made my knife sharpening far more consistent, and it’s a great tool to have for any project requiring accurate angle measurements.

Great for the wood shop
I use this in the wood shop all the time. Much more accurate than the gauge on the machine. This has made changing angles quick and easy. The quality is top-notch, like most of Klein’s tools. The power of this magnet is wonderful. I attach it to the blade, and it stays there.

Simple tool done well
This little thing is a very simple tool. Turn it on, set it down and it tells you the angle. It’s very light very compact and the LCD screen is easy to read. The best part of this is the strength of the magnet. FINALLY, someone figured out how to put a GOOD magnet in a tool! I’m blown away by this…. Its the first tool I’ve found that actually has a sufficient magnet! This is Klein though….their products are usually better quality than most. Wish they could inform the rest of the tool world on how to properly choose a magnet.Ive used mine quite a bit in the last month. I’ve dropped it several times, it looks very rough now from grease and dirt, but is still dead on. And I mean dead on. I’ve cleaned it a couple times with brake kleen and it doesn’t bother the housing at all, and I’ve SOAKED it. Green or red can have no effect.I do like the auto off function. I’ve left it under a couple cars overnight by accident. Speaking of which, I did take a 25mile test drive, git back under the truck and found it still attached! It stayed on for the trip at 70mph!Tgis is a tool I wouldn’t mind having 2 of. Just incase…

solid compact versatile
Works as advertised. It showed and ERR code at first time turning it on but it was because I did not have it in a vertical position. It will only read in vertical position, if tilted back or forward it will read ERR. Only wish it had magnetic on both top and bottom but the display will turn over for an upside down read so no big deal.

Measure angles precisely. Magnetic mounting.
If you are working with metal and need precise angle measurements, this little beauty is perfect. I’m setting up suspension on a Trail Buggy project and this tool made measuring caster angle simple and easy. Also made setting up driveshaft/pinion angle a snap. If you are a fabricator, this tool will come in handy!

This a great little unit, we have doing reno’s for over a year and I could have used this before now. It is more accurate than what I need but Tver easy to use and easy to read even without glasses which is a big plus. I am typically using it on top of my spirt levels as it’s more accurate and easier to see if you are level. Especially one the longest level where it can be hard to hold it in the right place and get a good view of the bubble. All up I would get another one if it stopped working without hesitation.

I’ve used this for 1.5 years and now it would not power up despite many battery changes.

Just awesome. I use this for bending metal conduit. This and a tape measure means you get repeatable bends over and over, completely removing the guess work associated with marking the former with a pen.Mark your bend start, put the conduit into the former and hold the conduit up with the bending handle. Put the inclinometer on the conduit, then zero the inclinometer. Pull to 91-92 degrees. Let the pressure off and check for spring back of the bend. You should have a perfect 90 degree. Easy, repeatable, accurate. A set is easy too, using a similar method you can produce perfect parallel sets, again repeatedly and accurately. This truly is an essential for anyone putting in electrical containment.
