Interesting post!! I have the dewalt laser with the Bosch telescopic pole, very easy to use, I sometimes with the line had more definition but that's probably just my eyes lol. One problem that does happen a lot with me though is the amount of times I'm levelling something and it just happens to be at the same height as the tightners on my telescopic pole.... Right pain in the bum I tell thee!! Funny though, when I first got my laser I thought it was my best tool but over the years I tend to use it less, use my conventional spirit levels much more in the last year.
