Here's a look at the new RodeLink Filmmaker Wireless Audio System. In the video below i'll show you the parts, basic setup, functions, and a quick distance test at the end of the video.
I haven't done extensive tests, but in the short time i've been using the kit, it's been nothing but solid performance. RODE is offering up quite a bit in this kit, along with a lav microphone that can be adapted for use with other systems. Another interesting feature is the RODELINK can be powered via AA batteries or powered through it's USB port. I believe the USB port can be used for firmware upgrades as well.
For the price it's hard to argue that this is a must have piece of kit everyone should have in their bag. If you've been looking to get a wireless kit, I wouldn't wait too long. The price is right, and I feel these items will continue to sell out for sometime. It's still unclear if prices will go up to the list price of $599, but right now Pre-Orders are currently listing for just $399 (found here).
