FINIS Aquapulse heart Rate Monitor

Hello members: I always swim with Heart Rate monitor. I am using Polar HR, but as you know it is not very comfortable to use a t-shirt to swim. I want to know if someone of you is using the Finis Heart Rate Monitor: www.finisinc.com/.../aquapulse-heart-rate-monitor.html What do you think of it ?? Does it meassure Heart rate with good accuracy ?? Finis HR seems to be very comfortable. Thanks very much for your opinion
