Medicare and insurance coverage provides stability for medically necessary equipment, though consumer out-of-pocket spending for upgrades or non-covered features shows sensitivity to disposable income and consumer confidence. The 65+ demographic (primary customer base) typically has more stable spending patterns than general population.

Rising interest rates have modest negative impact through higher financing costs for inventory and working capital, though debt/equity of 0.09 indicates minimal leverage.
