We purchased two Garmin Varia RTL 515 radar units from Bike Tires Direct on July 28,2020. My partner's unit, which has been used fewer than 10 times, will not hold a charge. Garmin tech support claims that since the unit is past the 1 year warranty, it can only offer to supply her with a "reconditioned" unit if she purchases it for half the price of the unit she originally bought from them. If she were to take Garmin up on their offer, she would have to return the original unit to them, and the reconditioned unit would carry a 90 DAY "WARRANTY". Given her experience with this hunk of junk, and the caveats they erected, we couldn't see giving Garmin any more business in exchange for more frustration due to their ridiculous product warranty and customer service. Worthless!
