I couldn't find yet a DMM who shows two digits. They all show only one digit so for me are useless. The regular ohm meters that can be bought from the vape shops are built very cheap and inaccurate. I went into two vape shops and ask the guys to open 3-4 ohm meters and I compared the same build. They all had different readings. And when I say different I mean very different.
We even used the ohm meter from few regulated boxes and the values were still different.
It is very difficult to find a good ohm meter in my opinion.
