COSLUS E40 Cordless Water Flosser — 10 Settings, 300ml Tank, 39.98 CAD (20% Off)

Anyone who's wrestled with string floss or picks food out of braces will get why a water flosser is a game-changer. The COSLUS E40 is 39.98 CAD, down from 49.99 — 20% off. Amazon's Choice with 5,000+ reviews at 4.4 stars and 1K+ sold last month. The numbers speak for themselves.

Two things stand out. The stepless dial gives you 10 pressure levels — start at 1-3 for sensitive gums (feels more like a massage) and work up to 7-8 once you're used to it. A single device covers everyone in the house. Second, the 300ml reservoir is genuinely full-session sized. A lot of portable flossers top out at 150ml and you end up refilling mid-clean, which breaks the flow.

Cordless and USB-C rechargeable with a claimed 30-day battery life. IPX7 waterproof — use it in the shower if that's your thing. Comes with orthodontic tips and a massage mode, so it works for braces, implants, and sensitive gums alike. MDL certified and BPA-free.

Deep Black at 39.98 is the best deal. Mint Green is 49.99, Pink is 46.99. At roughly half the price of a comparable Waterpik, it's one of the better-value entry-level options out there.
