With the ISSA 2, the search for the perfect toothbrush is over. Foreo's rechargeable electric toothbrush helps achieve a whiter and brighter smile. Thanks to Sonic Pulse technology, it combines micro-vibrations with a unique hybrid brush head to remove plaque, stains, and resist tartar buildup and cavities. The inner ultra-soft silicone bristles gently massage the gums and prevent excessive pressure on the teeth, as well as gum recession and enamel damage. Now with double the power, 16 adjustable cleaning modes, and up to 11,000 high-intensity pulsations per minute, the ISSA 2 gives you complete control over your oral care. Fully waterproof and ergonomically designed, it features a built-in timer and a 3D-flexible brush head for a healthy mouth. The ISSA 2 is used like a traditional toothbrush - recommended use is 2 minutes twice a day. It is USB rechargeable and does not require a charging station, with a 1-hour charge lasting up to 365 days.
