Quality Portable Flosser
This flosser is very effective and easy to use. Excellent quality and every bit as comparable to the brand name product. It is rechargeable, powerful, has different strength settings, and the water reservoir holds a lot of water! Numerous tips are included. It is well built, attractive ,and is marketed at a good price. Great for travel.I am very pleased with this product..

Perfect Purchase
This is a very good item. It really does clean hard to reach areas of your mouth. I am a daily flosser. I tried it on areas that I did not floss and it removed the food very well. It took me a while to aim perfect before getting a slight shower all over my face. I got it down now. I have not charged it in months. Long charging time. Perfect Purchase

Not bad for the price.
For the quick review, this is fine especially for the price I got it at. Not the best I've used, but not the worst either. I'd prefer to give it 3.5 stars, but it's closer to 4 than 3 for me. Biggest issue is the nozzles don't seat firmly, so they tend to spin in your mouth and you have to adjust as you're using it to floss. They won't fall out or anything, but it takes an adjustment to learn to use if you're switching from a Waterpik. The nozzles are definitely cheap plastic, but they work. Doesn't leak, battery life is good, and it's relatively quiet for a water flosser, though there's no mistaking the sound. Haven't been to see a dentist since I got it, so I don't know about the claims on how clean it keeps your teeth, but it does a fair job at getting food particles from between your teeth out. Overall, it's fine. I don't regret the purchase, but I don't know if I'll buy it again once this one wears out. Now for the long review. Before this I've only used Waterpik flossers, so I'll be comparing them a lot. Off the rip, this isn't as powerful as a Waterpik, not even the portable one. I started using water flossers 10 years ago with a portable Waterpik, then upgraded to a counter top Waterpik Ultra about 6 years ago. This past week it died on me, and this was the easiest (and cheapest) replacement option. I didn't expect amazing quality, and I was right not to. That being said, it's quite good for the price I bought it at. I got this on sale with a coupon for about $20. That's just under half the price of the cheapest Waterpiks. At twice a day, the battery lasted for just over a week. Like I said above, I don't know about the claims on how clean it keeps your teeth, but I'll update my review next time I go to the dentist. So far, it's done a good job of removing food particles which is the biggest thing I bought it for. Water pressure is a little low for me, but again I've been using Waterpiks at the highest pressure for a few years now. It can take a few passes for me to make sure I haven't missed anything in my teeth, and unfortunately that means I find myself refilling the reservoir at least once during most of my uses. Annoying, but I had to do this with the portable Waterpik too so I expected it and didn't dock points. It's only got two pressure settings: clean and soft. There's a massage setting has a pulse between the settings, but I don't use it. I only used the soft setting once and found it to be useless; I could compare it to a 2 or 3 pressure on a Waterpik. The 'clean' setting is comparable to a 5 or 6 on the Waterpik. Useable, but not super strong. Just enough for me to get some stubborn areas on my teeth, so I docked a half point for the highest pressure not being good enough for me. I've read some reviews of people saying that this has extremely strong pressure for a water flosser and others saying it's near perfect. I have to say that is not my experience at all. Could be a difference in manufacturing or any number of things, but for me the pressure could be half again as strong on the clean setting and I'd be much happier. This does NOT come with an adapter for the charging cable. You have to provide your own 5v power brick. I had enough extras lying around from other electronics that I could give it a dedicated adapter, but it is definitely annoying that they can't provide a $2 adapter in the box. For package reduction reasons? That's seriously the excuse they went for? Whatever. It's advertised so no docked points for it. Now the biggest issue I had with this flosser and what made me dock a whole point. The nozzles. Not the variety, that's fine, though I'll say that I have only used the standard nozzle and the tongue nozzle to date. I don't have gum issues that require the periodontal tip or orthodontia that require a the specialized tip for orthodontia. That being said, the problem with the nozzles is their quality and how they're seated in the device itself. The plastic they're made from is thin, and not very durable. For the tongue scraper, this means you can't exert a lot of pressure before the nozzle bends when using it. For the standard nozzle that means it can bend just from the pressure of your cheek and gum pressing on it. The way it's seated in the device itself doesn't help. No nozzle is loose, nor do they leak water, let me be clear there. Once the nozzle is seated, it won't come out and they spray water only as intended. No the issue is, the nozzles spin. In theory this wouldn't be a big deal, the nozzles are meant to spin to allow minute adjustments while they're in your mouth so you can keep that 90 degree angle on your gums. In practice, because the nozzles spin so easily you'll often find the nozzle pointing in the wrong direction in your mouth as you try and floss. This took a real adjustment to get right, and to be honest I'm still adjusting. I still have the nozzle spin the wrong direction on me sometimes, and it is extremely annoying to have to pay so much attention to the nozzle when I'm trying to use it. This is something I wouldn't have even thought of as a problem, except that Waterpik doesn't have it at all. Waterpik solved this problem by having an adjustable nozzle with set turns. Each time you turn the nozzle to a new angle, it clicks into place. Harder to spin the nozzle, but easier to use. Coslus spins freely, no clicking into place and no torque required to move. Because of that I find myself spinning the entire device while I use it to keep the the nozzle at a 90 degree angle to my gums. This is the biggest reason I over my teeth 3 or 4 times when I use the Coslus. The nozzle has spun off center a little, and I want to make sure my teeth are clean. You could try and hold the device at the nozzle and keep the nozzle from spinning, but that's extremely awkward (and the video they provide doesn't show the device being held or used that way so clearly they don't expect if of you). With all that being said, I got this mostly because I didn't want to go back to regular flossing and I couldn't afford getting another really nice Waterpik right now. This was a stopgap so I could keep 'flossing' and not mess with my budget much. In a month or so I'll probably get another countertop Waterpik and this will be relegated to a travel device. For now it does mostly what I need, in a slightly annoying way, and at a very affordable price.

Love this dental flosser!
I really like this dental flosser. Very reasonably priced, you get 2 of them and it holds a lot of water. It is easy to use, charged and ready to go.

Great for home use or travel.
I love my plug-in countertop water pik but wanted something that would be easy to take on short trips or (unfortunately) hospital stays. This was perfect for me. It came in a box that I was able to keep as a safe travel container as well as several specialized attachments. To be honest, I didn't use any of the attachments as I use my old stand-by for that, but for routine cleaning this worked great. I loved that I didn't have to pay for batteries or worry about them running low while traveling. Instead, just a short recharge and it was ready to go and lasted a long time. It also has an indicator light to let you know when it needs to be recharged. The noise was about the same as my other pik but nothing too loud. The cleaning was on par with the larger counter-top model I use at home. It seemed a little big and awkward at first, but I adjusted very quickly and it was easy to use and manipulate. It adjusts from gently cleaning - gum massage to "clean the grout" strength. It was also very affordable. Overall, I am very pleased with this purchase.

Add it to your Dental Routine
This is a game changer for cleaning teeth. The charge lasts a long time, it’s durable, and the strength of the flosser is strong but in a way that won’t make your gums bleed. (I mainly use the “soft mode” though) The only issue I’ve had has been bc of myself. lol I have accidentally turned it on without having it in my mouth and have sprayed the mirror and almost ceiling with water. I think if there was a way to lock it in a mode or even to keep it off that would be a cool addition. To switch modes, you can do so without having it on which is nice. Just keep in mind yall still need to floss your teeth with string. This is just additionalan additional tool to help with cleaning. And they give you plenty of flossing attachments to start with. My favorite was the one that was more pointed and a soft tip bc I felt like I could be more accurate and wedge it in between my teeth better. I have also accidentally dropped this from the counter. I snapped off the adjustable tip and I thought it was going to be done. But I was able to get the piece out and it still does on strong. I recommend completely breaking it down after use though to allow it to dry. My apartment has extremely hard water and if it sits, it’ll build up. Thankfully though, this thing is easy to break down and put back together. How I break mine down: Detach the container of water and empty out, pull off white circular plastic piece connected to the end of the clear tube, run the flosser upside down (without the container or bottom plastic circle attachment) to expel any water left inside, detach tube as well as the head of flosser to allow to dry. By the morning it’s good to go

Great Dental Flosser
I always find it difficult to use the string type of Dental Flosser as my teeth are too close together and it bleeds when I forced the string between the teeth. With a Water Dental Flosser, I don't have any problem as the water jet is strong enough to flush in between the teeth. I need to do this as my gums are quite sensitive and get inflamed if food are stuck in between the teeth which toothbrushes cannot get it out.
