EssentialA, yikes...you should get out more; Mike's story is well documented and it is available to you.
Nandy, I always do love your effort. Again, you are, as usual, nonsensical while clearly personifying "artificial" intelligence.
In the meantime:
If you are wanting a real Quality, Superior, Better-Made, Better-Designed, and Better-Results designed alignment Dennison Device...look no further than Nerve Audio. It is a much better protractor and is a quality USA made product...save a bunch, better alignment, and Peace-of-Mind, all for around
$179.00. Also, no affiliation, just a fan of great performance and wonderful business practices.
Cheers!
