The few known failures point to a manufacturing defect in the sensor component. It is definitely covered.
As far as reliability in general, there are units that have been in continuous daily shop use for months, representing many tens of hours of use. The few known failures have happened very early in the service life, within the first hour or less.
The two reported failures represent a rate below 1%. Not enough data to be of real statistical significance.
If a higher rate begins to appear, I may temporarily suspend sales until I can put a more robust test in place to catch defects.
But I want to be clear that I will stand behind the product and make every effort to ensure satisfied customers.
That's all I needed to know. Thanks for making such a high commitment to customer service and satisfaction.
