I see that Applied Ballistics LLC has moved to the Labradar and has it as one of its small list of recommended products. I seem to remember a 'Doc Beech' Applied Ballistics newsletter piece a while back saying that after extensive tests. the ballistics lab has moved from Oelher professional chronographs to the Labradar.
(If you get hold of Bryan Litz's 'Modern Advancement' books Vols 1 and 2 which have lots of fascinating range tests of different handloading / ammunition variables, some involving hundreds of rounds fired, maybe even 1,000 in some tests, you can see that a reliable, accurate chronograph is an essential tool. Volume 1 has a chronograph evaluation chapter, but minus the Labradar as it was written / published before that one was in series production.)
