Cheap and not that cheerful. We've used this in our church for the last 3 months. Batty life is stated as 8 hours, and is certainly no more than that. It's not so much the cost of replacement but the hassle of having to do it half-way though services. A low battery indication on the receiver would have been a good idea, so that the PA guy can keep an eye on it. The range is also quite poor - we get interference from 10m away. When the battery gets low, the RF drops out more and more (with a pop/bang, not a mute!) which is annoying. I'd spend a bit more next time, but fine for occasional use.
