The seneye+ includes the disposable seneye slide, e-mail alerts, automatic online graphing, and personalised advice. Activating your seneye+ is really easy and the disposable slide removes the need for recalibration (and the cost of recalibration fluids/buffers etc…) and better still it improves accuracy. * the seneye+ has a recommended use by date of 12 months from date of manufacture, always store in a cool dry dark place.
