I got 4 old one.... all Casio.
JP-100W
JP-200W
BP-100
BP-120
2 heart rate monitor & 2 blood pressure monitor. The blood pressure model is not as accurate the blood pressure device but it can give you the overall picture of your heart status. Casio also claim it is not a medical device, but can help you monitor your pulse & heart rate. But the heart rate is quite accurate. I already tested a few time with the medical device.
The new Casio & Timex also got this heart rate monitor. Sell for about RM400++. Cheaper than the Suunto.
