If you are looking for the best reliable laser meter, that would be the
Hilti PD-E, but expensive at $779 (Home Depot). It is just that they don't do much advertising or pay for good reviews. It works fine and the red dot is a lot easier to see than the X4. It is very
rugged. They have been in business since 1941, and they were founded in Schaan, Liechtenstein:

In the US, their main production is in Texas (Plano, Dallas).

I still have my Hilti PD-20 which I bought around 2004. I can't use the PD-20 anymore because it doesn't measure in hundredths of a foot, only hundredths of an inch or thousandths of a meter. And, - I am completely on the standard 1/100 foot in everything:
Keson Engineering Fiberglass Tape 1/100' (100' and 400')
+ Leica Disto X4 set to 1/100'
+ optional Disto DST 360 Kit (tripod and carrying case) which works only with the X2 and X4 (not the Leica Disto D810)
I am not absolutely sure that the PD-E can measure in hundredths of a foot, as the documentation doesn't clearly state that. You would have to call Hilti. But I would guess it does.
Note: I tried the D810 and didn't like it at all.
If you are using an X4 or other meter for point-to-point measurements of a second or third-story floor, you
can do it by holding it in your hand, but it is really difficult to hold it on target at the very edge of a corner from 50+ feet away. You really need a steady tripod to accurately aim and hold it for reading. However, at this point in time, there are likely better things to spend your money on than a DST360 tripod.
