What raises or lowers the price
Tracking is the main cost driver. The TechRing's $275 covers sensors, Bluetooth, a USB-rechargeable battery that lasts about 12 hours, the FirmTech app, and a 1-year warranty on electronics with 2 sleeve replacements. The Performance Ring and MaxPR cost $60 with a 3-month warranty. Bundles lower the per-item cost: pairing the TechRing with a second ring saves $40.
