Reviews
“It's a nice quality unit, but I'm returning it: This was my first ever water flosser. I'm 73, and have always brushed arduously, multiple times per day. In the last twenty years, I had good dental checkups with rare cavities. The Covid pandemic changed that. Clinics in my area (rural Maine) shut down, and my finances got worse. Result: no check ups for three years (and therefore no dental hygienists) led to seven cavities. Dentist said, paraphrasing, "You're not being…”
“Lightweight easy to clean: I really like this water flosser! It’s lightweight, easy to use, and has a good water capacity. I like that you can adjust the pressure to your preferred setting, and it comes with multiple tips for different needs. It works great, and I highly recommend it.Read moreRead less”
“Super versatile and easy to use!: I am loving this cordless flosser! I use it while in the shower which is perfect. Multiple floss heads and adjustable intensity make it very versatile. I can definitely feel and see the difference in teeth and gum health. I know my dentist is going to notice as well!Read moreRead less”
“I am incredibly impressed with the COSLUS C20.: I am incredibly impressed with the COSLUS C20. The 300ML water tank is the perfect size because it holds enough water to clean my entire mouth in one go without constant refills. I love that it is ADA Accepted, which gave me peace of mind about its safety and effectiveness.The dual-stream pulse technology works wonders at blasting away food particles and plaque, yet the "Soft" mode is gentle enough for my sensitive gums.…”
“Very good results.: Very good product, excellent for cleaning and massaging teeth and gum. I was a bit disappointed that the plastic closure cap on the bottom broke off after just one week of use. It still functions when attached, but Im fearful I will lose the piece and have no way to close and secure the water/fluid in the unit.Read moreRead less”
“It works. It really works!!!: Works amazing. I honestly didn't think it would be all that strong from the video reviews I seen. But after giving it a try I'm blown away. It's extremely powerful (in a good way) even on the lowest setting. I turned it on and immediately my gums felt cleaner. A powerful stream of water hit my teeth and it felt like it was deep cleaning. Almost felt like going to the dentist. The grip is very comfortable in hand. I couldn't recommend it any…”
“Good value: For the price, I really like this water pick. It's effective and has different settings, so you can get used to it. I like that it's small and fits neatly into a drawer. It's super easy to use and refill.Read moreRead less”
“A worthwhile alternative to more expensive brands: I purchased this water flosser because it was available at a discount. I was initially unsure about its performance, as Waterpik is generally considered the leading brand in this category. However, after using this product for about 3 weeks, I can say that it has fully met my expectations.The unit is easy to charge and convenient to use as a cordless device. So far, I have not experienced any water leakage, and the noise…”
