I got my AA 2.0 a few days ago and it left me with the same impression although I don’t have anything similar to compare. It came in a sealed retail box, magnetic tail cap included. Workmanship details are remarkable. The tail button has the logo and it stands just fine. It even has a serial number printed on the head!

When battery voltage drops to some pre-determined level it switches automatically to Medium from High or from Turbo. I changed the battery at this time. I observed no flicker. For me, it wins the best clip design and tension.
