The device is very light and feels a little cheap , not the usual dewalt product, main gripe though is the carry strap which you have to fit is impossible to get through the time hole , after many attempts I had to use a piece of wire to push it through , silly design,

Great and accurate

I was surprised how accurate it was. I checked against calibrated manual measure and it was 3 mm off in its maximum distance, 30 meters. Great tool and easy to use.

Tape measure ?

It's OK. Used it to measure all the walls in my house. It turns off a lot mid measure, which is frustrating.

Does not seem to work to do a simple measurement. I wonder if it is faulty. Trying to find a customer service number to phone….

No good 6mm out tested against 2 other brands a bosh laser (1mm out ) and one a joiner had bought from temu (3mm out) a good old fashioned tape (spot on )
If rough measuring for skirting / carpets etc. would be ok but if your needing to the mm measurements look elsewhere
