Calculated Industries 7489 AccuMASTER Value Pack – 2-in-1 Digital Angle Gauge plus the Digital 7-Inch Angle Finder Ruler | Accurate Precision Tools for Carpenters, Woodworkers, Fabricators | 2-Pieces

The level 8s awesome. I love the bright screen and the magnet on it means I can perfectly square my table saw and mitre saw blades with ease. The angle finder also makes it a dream to do trim work and cut "45s" on off angle walls. These are both very easy to use and worth every penny. also they are one of the few that at least advertise a case to keep them clean and protected when not in use. highly recommended.

So far so good. It’s quite accurate except 2 issue. The 2 rule don’t seem to exact width size, hence not parallel depending on which side (inner or outer) I take as reference point to reset zero. Second issue is the reset button can be easily press by accident. Should make it press and hold to reset for example

Just junk. Protractor quit after using 9 times over 3 month period, then find out my return window closed a month after I bought it. Just junk.

Easy to use and very accurate.

They seem to be relatively accurate for the price. It would help if I had something I knew was straight to zero it. My house was built by a group of roaming gypsys. Up in a month and they were gone in a flash of light. But I like the set, real nice pouches for them to sit and work exactly as described. I would recommend these for someone looking for semi precise angles. You get what you pay for, and these are a bargain for the quality you receive.
