How long have you been using it? Two years and one month.
It has broken down twice in two years, but it's no longer under guarantee.
And it's the exact same problem, but other than that it's a good mic. I don't like the power switch being at the bottom, it's not very handy. And I also don't like it's battery life...Batteries don't last more than one evening.
I wouldn't buy it again, for about $50 more I prefer a Shure - PG 24 E / PG 58 M10
I just bought this mic.
It's a beautiful microphone that feels nice in your hand. I use it to record conferences, for questions from the audience (in a cinema). I needed a microphone that didn't lost connection and I'm very satisfied: No dropouts in the entire cinema, which is about 100ft big approximately. You can tell the manufacturer's know-how.
In terms of sound, it is very nice on vocals. I don't need a windscreen to avoid pops. However, it does have lots of handling noise. Very good battery life (10 hours, according to the manufacturer, but I haven't checked it).
I've had some other mics that haven't satisfied me (due to unacceptable dropouts). Very good value for money, I'd certainly buy it again, like all Sennheiser products (I have several headphones that have all satisfied me, in accordance with their price).
I bought it as a mic for presentations during shows.
I then tested it during a gig for backing vocals and the result surprised me, as well as he other members of the band.
It probably isn't the best for main vocals, but it's quite all right for backing vocals.
No dropouts even at 60 feet.
The mic's switch doesn't generate pops through the PA.
The receiver has two outputs (jack and XLR), a volume control, a Squelch control, and several LEDs (including a very useful Peak indicator).
The receiver is the same for the entire Freeport range.
I'll update my review later, but I think its features and sound clarity are amazing at this price point.
It comes with a (good quality) mic clip and thread adapter.
Update from 2011: I confirm what the manual states: It lasts exactly 8 hours with any cheap batteries.
