Less effective than the corded version of it, the Waterpik® WP-580 still offers decent performance for users prioritizing portability. While its cordless design makes it convenient for travel or smaller bathrooms, the water pressure and tank capacity fall short compared to full-sized, corded models. The rechargeable battery is a plus, but it can weaken over time, leading to inconsistent pressure. It's good for light flossing needs, but those with more intensive dental care routines may find it lacking. If you value power and continuous flow over portability, sticking with a corded model might be the better option.
45 SECONDS - Small water holder I think the pic is to small if you want to do a more through job irrigating your teeth

Hello lloyd241 - We're sorry to hear you're not completely satisfied. The reservoir has a capacity that allows for up to 45 seconds of use and can be refilled as necessary.
Absolutely amazing purchase! I’ve never owned a water flosser until my orthodontist told me to get one. I’m so glad I spent the extra money to get multiple types of ends because I think I have used everyone of them.
This is an excellent way to floss your teeth that feels like you’ve been to the dentist! I only wish is that the water container was a little larger. Otherwise I totally recommend this amazing product.
