AmpStrip's makers are attempting to address these limitations and want to help competitive athletes take heart rate training to the next level.
I suspect the reason why their Indiegogo campaign has smashed its funding target by 290% with 30 days to go, is because the AmpStrip appeals to a very committed vertical (it's aimed at elite athletes). Also the company behind the AmpStrip have been in business for over 20 years, so backers will feel confident that this product will make it to market within the stated timeline. The estimated released date is June 2015, and the AmStrip will retail for $149.00 (£99.00), International shipping is offered for an additional fee. Unfortunately the early bird deal of $99 is no longer available.
