Any opinion on the Heart Rate Monitors by Oregon Scientifics, specifically the PM800?

I saw them on sale here for just 29 Eur (about $29 at the moment). It seems like one of those "too good to be true" deals. I didn't have the time to inspect it closely, so I am not sure about its functions. I don't think that it has a computer download.

Any experience with them?

Thanks in advance.

Cheers,
Jamie
