I've done quite a few Leon Soundbars over the years, (not over the last couple years tho) and don't know if anything has changed, but I was never a fan of the mounting system..  Always seemed to be a pain in the ass, small adjustments as well...  The other techs I worked with at the time always seemed to have similar issues as well.
They always did look great though, beautiful finish, always perfect to the TV dimensions.  I loved that they had an option for the super slim TVs back when they came out.
Was never really blown away by any soundbars, nowadays if I need to use one I've been leaning towards Sonance's model..  Totally different as far as finish, but I do like the sound from them...
