Review: Terrible mistake—An awesome unite and great company! - SORRY SORRY SORRY! A TERRIBLE MISTAKE I MUST CORRECT—I DISCOVERED WHEN I CHARGED MY WIFE’S E40 THAT I PLUGED INTO THE WRONG CHARGER. IN OTHER WORDS, MY WIFE AND MY E40 STILL WORKS AND WORKS WELL. SORRY FOR THIS MISTAKE AND LOW REVIEW. COSLUS IS A RELIABLE/DURABLE UNITE! BEFORE I DISCOVERED MY MISTAKE, I DID ORDER ANOTHER COSLUS E50. NOW I HAVE A UNITE IN RESERVE. The new E50 comes with a 2 year warranty which is unheard of regarding water piks. The Coslus ADA lasted for less than 9 months. Worked great for that period of time, but now it will not charge. It appears to be made well, and the charge lasted for months. The price was also acceptable. I guess for $20 one cannot expect longevity. I may reorder The Coslus, but I will also look at similar products. My wife has the identical E40 and it is still working. However, I have just put it on the charger hoping it will charge. ## Features - ADA Accepted, Advanced 10 Pressure Settings for Personalized Cleaning: The COSLUS E40 portable water flosser features 10 precise pressure levels, allowing users to easily adjust the water flow to match their unique oral sensitivity and cleaning preferences.

I wasn't sure what to expect with this all in one unit. It is slightly bulky compared to holding a toothbrush sized water flosser but I have adapted to it. I like that it is simple to operate, rechargeable, has multiple head attachments, different intensity levels and 2 modes to choose from. I would buy this item again unless I could find the original smaller style at the same price point. ## Frequently Bought Together - COSLUS Water Dental Flosser Teeth Pick: Portable Cordless Oral Irrigator 300ML Rechargeable Travel Irrigation Cleaner IPX7 Waterproof Electric Flossing Machine for Teeth - COSLUS Electric Toothbrush for Adults and Teen: Wireless Rechargeable Tooth Brush for Adult and Teen Youth with Portable Travel Case, 5 Modes 47000 VPM Power Toothbrushes 6 Brush Heads Pink - COSLUS Water Dental Flosser Pick for Teeth: 4 Modes Cordless Portable 300ML Larger Tank Water Teeth Cleaner IPX7 Waterproof Flossing Cleaning Picks for Home Travel FC5360 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/670920732-coslus-ada-accepted-e40-water-dental-flosser-10-pressure-levels](https://www.desertcart.hr/products/670920732-coslus-ada-accepted-e40-water-dental-flosser-10-pressure-levels) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-20*
