I recently purchased the Coslus Advanced Water Pik, and I have to say, I’m impressed. I’ve used a more expensive, well-known brand in the past, but unfortunately, it didn’t last more than a year. Over time, that unit gradually lost water pressure and eventually became almost useless, which was frustrating considering the price. The Coslus Advanced Water Pik has been a pleasant surprise. Right out of the box, it felt solid and well-built. The water pressure is strong and consistent, making it great for cleaning between teeth and along the gumline. Even after months of daily use, it hasn’t shown any signs of weakening, which was the biggest issue with my previous water flosser. I also love the varying pressure settings. While I personally enjoy using it as high as it goes, I appreciate that it has more gentle settings, which my 10-year-old tried and loved, so much that we bought her one too! That’s a win. Overall, I would highly recommend the Coslus Advanced Water Pik to anyone looking for a reliable and affordable water flosser. It performs better than my old, pricey brand and so far seems like it will last much longere. Read more

Strong water stream I was skeptical at first but it BLASTS water between my teeth and works well I even accidentally squirted myself in the face a couple times LOL. Incredible clean I use it after I eat and food particles come out between my teeth and my teeth and gums feel clean. The duration could be a little more but that would need a larger tank so it would take up more space. I got faster as I got better at using it though. I can even get to my molars really easily which was really hard for me to reach with normal flossing. Read more

Works well. I use it twice a day. Good for the price. This water flosser replaced a Conair Interplak unit that I've used for at least 10 years but finally sprung a leak in the hose. The only downside is the tank requires both hands to remove. The base of the unit isn't heavy enough to stay on the counter by itself when removing the tank. There are suction cups on the bottom of the base to hold it down to the countertop but they don't retain their suction very long. Not a real problem but an inconvenience. Read more

FIRST...THE BACKGROUND: I dumped my vintage Water Pik (1990s) a couple months ago, gave it to Goodwill, after years of irritation, having this total dust collector sit on my bathroom countertop: No lid for the water reservoir to keep it clean and dust free so you could just leave the unit out. Nor did the wand fit easily back in the hole for it, and the cord was always messy, all over the place. Bottom line: If you had the time and didn't mind the aggravation of plugging and unplugging, assembling and disassembling the unit every single time you used it, fine. And good on you for being more patient than I am. For me, after about the first month or so back in the 1990s when I got it, it was a constant source of irritation. Not to mention the fact there was no place convenient or dust free to store all the extra nozzles. The whole point of flossing is we get busy in life and need a way that is simple, elegant, and designed in such a way that it makes the process as seamless and as easy as possible, and actually encourages us to floss. Enter the... COSLUS WATER FLOSSER This thing is fabulous. The size is just right to simply keep on your vanity top. The footprint is small -- a key feature because, yes, realizing that every square inch of our sink surround is high value real estate, you pick and choose wisely what stays out -- but because we now know oral health is so important to general health, this machine has absolutely earned the right to stay on top of the counter. 1. It doesn't read like clutter, the design is sleek. 2. The suction cups on the bottom to keep it lodged safely, is a brilliant design feature. 3. The separate enclosed area on top which houses all the extra doo dads, and also tucks neatly beneath the lid to keep it all dust free is genius -- which (correct me if I'm wrong, but I don't think even now the most current Water Pik has this level of thoughtfulness in storage for the extra wands. I looked at pictures here on Amazon, and I can't see it. 4. The machine noise factor, as others stated, is perfectly fine, reasonably quiet. A nice surprise after my old Water Pik. 5. The reservoir is plenty big enough. 6. And the fact that the coil is tight on the cord so even though it takes a bit of practice learning how to use it easily, the benefit is, it makes repositioning your flosser wand back in place after use just so easy. And looks so neat and tidy. 7. But -- to top it off, after all this -- the fact that it's HALF the price of a Water Pic? No brainer! I could NOT be more thrilled with this new gizmo to ensure I stick with flossing daily, even multiple times, and make oral health the priority it should be. HIGHLY RECOMMEND. Read more

I have been a believer in the water flosser ever since I discovered that daily flushing out food debris under the gum line reduces my tooth decay issues to nearly zero. I have tried a parade of corded and cordless WaterPiks until each one in turn wore out. This COSLUS unit is a worthy competitor. I like that it is corded; there is no battery to discharge and wear out. A design feature like the easier installing nozzle is surprisingly helpful. The water pump is at least as strong, and the price is lower than the WaterPik. So for me, the COSPLUS unit is working very well. Read more

Works far better than I expected. It is not expensive and works very well. I use it all the time. It definitely gets more than just using standard string floss. The only concern is starting the pressure low and working your way up. DO NOT start from beyond maybe 6 or higher. Read more
