The DW087K is specced at +/- 0.3mm/m, so 3mm at 10m. Whether you regard that as inaccurate will be down to the requirements of the job. For most electrician's work I would have thought it would be good enough. And, generally, you won't have one that's right on the limit.
That's one of the reasons I went for the dewalt over the stanley (0.5mm/m)
Have used it on quite a few jobs & it's been great so far.
