Smart Swab is one of our two original, USA patented and registered spiral ear cleaner, providing effective ear cleaning methods invented by American inventors. Unlike the other tools, it has a safety feature preventing it from going too far and unlike the liquid solutions, it does not cause uncomfortable feel and messy discharge in and around the ear (though in case your earwax accumulation issue is bad and much harder than average or normal soft wax you might wish to use both methods simultaneously). Smart Swab actually works without the drawbacks and hazards seen with cotton swabs or inadequate products such as earwax candles.
