I used to have a Sigma (it was one of the higher end ones) and I found it to be more accurate and have a faster reaction time (the one I have currently must not sample at as high a rate - I can tell that there is definitely a lag in the read out compared to my actual heart rate) than any of the others I've used. Maybe it was just the model Bron was using?
