Nice, in-depth review of the L Series products by production sound mixer Matt Brodnick:

In-Depth Review: Lectrosonics L-Series | BAMFSOUND (http://www.bamfsound.com/lectrosonics-l-series-review/)

Tim Dashwood already did a great Lectro review back in April for DV Info Net:
Lectrosonics L-Series Wireless Lav Microphone bundle (http://www.dvinfo.net/article/production/audio/lectrosonics-l-series-wireless-lav-microphone-bundle.html)

"Tim Dashwood already did a great Lectro review"
- FWIW, Not to dismiss Tim Dashwood's opinion, but Matt Brodnick is a film sound pro.
Karl is a (highly respected) principle at Lectro, and would not be trying to skew an opinion in one direction... or so I would think of a .. self proclaimed.. fanatic.
