Amazon is currently offering the Coslus C20 Cordless Rechargeable Water Flosser for an exceptionally low price of $6.99. This significant discount is achieved by applying the coupon code "BQ385MEV" at checkout. No Amazon Prime membership is required to take advantage of this offer. The price represents an 83% reduction from the usual $42 list price and is reportedly the lowest price seen for the product. The Coslus C20 holds the distinction of being the number one best-selling flosser on Amazon, backed by over 51,000 user reviews.
Understanding the Coslus C20
The Coslus C20 functions as a water flosser, also known as an oral irrigator, providing an alternative to traditional string flossing. It operates by projecting a strong stream of water to clean between teeth and along the gumline, dislodging food particles and plaque. The device features three distinct pressure settings, with low and medium recommended for regular use and a high mode for tackling more stubborn debris. Included nozzle tips are designed for targeted cleaning of specific gum areas.
This particular model is a cordless, integrated design, differentiating it from corded units that feature separate water tanks. Its compact form factor saves counter space and enhances portability for travel. The built-in water tank has a capacity of 300ml, which is sufficient for a full cleaning session. The battery is advertised to last up to 30 days with typical daily use, and it can be recharged via a USB Type-A cable.
Earlier in June, the Coslus C20 was noted to have received the ADA Seal of Acceptance, adding to its value proposition, especially at this reduced price point.
Personal Comparison and Value
In a direct comparison with the popular $100 Waterpik Aquarius, a highly regarded consumer water flosser, the Coslus C20 demonstrates a difference in maximum power. While the Waterpik offers ten adjustment levels, the Coslus C20's highest setting is comparable to the Waterpik's level seven or eight. However, its strength is considered adequate for daily flossing needs. The Coslus C20 also lacks the ability to tilt upside down, a feature present in the Waterpik, and its handheld component is somewhat bulkier. Despite these differences, its space-saving design and convenience make it a compelling option for $7, especially for those seeking to reclaim a power outlet.
