What is the Pulse meter's lifespan?

As with any device, the product life span will depend entirely on use and care. The device has a 1 year warranty, but it is expected to last much longer than this if properly cared for. Examples of this include (but are not exclusive to) not submerging the device, not leaving it for extended periods (months) with a battery inside of it, and/or not unduly bending the probes.
