3-in-1 Digital Angle Gauge Angle Finder ArshTool Laser Leveler Rechargable Built-in Battery LED Magnetic Digital Level Box/Protractor/Inclinometer for Table Miter Saw/Woodworking with Fabric Bag

i bought this unit and tested it to see how accurate the lasers are relative to the body of the unit.i measured this on a custom rig that i have that is approximately 1.7m that is specifically setup to allow me to calibrate lasers. This thing was accurate to 1mm at that distance. The laser literally ran completely true all the way down the rail.Suffice it to say i am very impressed!The only thing i do not like so much about it is that the display moves in 0.05 increments, but that is just fine for the price.It does read the same almost as my DXL360S, and both this and the DXL360S are off by about 0.04 from my TLL-90S (much more accurate unit).

Love it. Works great and does everything I need it to do.

Accurate angle reading. Good for finding angles between to objects.

I bought this to set the proper angle for my sluce boxes while gold prospecting. It works!

Able to be used in a variety of contexts. Screens seem easy to read. Appears to be very well made. The magnets side and bottom are a real help. I also like the charging mechanism on it rather than one time use batteries.

The laser is useless. It casts a short line out each side. Which is fine but the line isn't level. It starts level at the most intense part but drops down as it fades off.

I use this on my Saws and other tools in my Workshop

I left this device fully charged in my toolbox for a few months. When I went to use it, it would not turn on. I've been charging it now for 24 hours, and it still will not turn on. It's too late to return, and I can't find any contact information for the manufacturer. Stick with something that uses alkaline batteries, and from a real manufacturer.

Too small size with sensitive readings since base is wobbly even on a thick straight glass, having different readings on the same spot.

Does not hold a charge

The unit works as described except that the casing is designed/manufactured in a way the the unit does not sit flat and level on a surface causing it to teter/wobble off balance which then changes the reading on the display.
