Great Portable Water Flosser: Powerful and Travel-Friendly
I’ve been using the COSLUS Water Dental Flosser for a few weeks now, and I’m really impressed with its performance. The water pressure is strong enough to thoroughly clean between my teeth and along the gum line, yet gentle when using the lower settings. My mouth feels noticeably cleaner after each use compared to regular string floss. The 300ML water tank is a great size; it holds enough water for a full cleaning without needing constant refills. I also love that it’s cordless and rechargeable, making it perfect for travel or small bathrooms. The battery life is excellent; one charge lasts me well over a week of daily use. Another big plus is the IPX7 waterproof design. I can safely use it in the shower without worrying about water damage. The unit feels sturdy, well-built, and easy to handle. Overall, this is a great value for the price. If you’re looking for an effective, portable, and easy-to-use water flosser, I highly recommend.

Good addition to your teeth cleaning regimine.
Works well. I don't know how much of a difference it makes. I use it after every time I brush though because I hate plaque buildup on my teeth. Does not replace actual flossing. So, I brush, then floss, then use this to wash everything away. Seems ok. Don't know if I recommend, but it's a good value for the price. Not too loud, plenty of water capacity and I do like the rechargeable aspect of it. I've had it for about 2 years I think now, so yeah, it's holding up well for something that gets used at least 3 times a day.

New addition to your dental routine!
This water flosser has been a great addition to my dental routine. It’s easy to use, and the different pressure settings make it comfortable while still feeling effective. My teeth feel much cleaner compared to traditional floss alone, especially around the gumline.

Great item. Company needs to utilize a different type of on off switch, however.
Works very well. Use it daily. Replaced the very difficult Dental Floss procedure and gets mouth to feel clean after use. Good value. Only problem with this item is the button to turn it off should NOT be an on/off button but a switch that turns the unit off once the button is released. Not a very intuitive design.

Really awesome oral dental Flosser!
This Dental Flosser is easily equal to any of the more expensive brands. It works really well, and holds a charge forever. I brought it with me on a two week vacation and it is still going strong, not needing a recharge. Great accessories as well.

Powerful, Easy to Use & Great for Oral Care
I’m really impressed with this water flosser! It’s compact, lightweight, and very easy to use, even for beginners. The water pressure is strong enough to leave my mouth feeling truly clean, but still adjustable so it’s comfortable on sensitive gums. The cordless design makes it super convenient, and the battery lasts a long time between charges. The water tank is a good size for a full clean without constantly refilling. I’ve noticed my teeth feel cleaner and my gums feel healthier since adding this to my routine. If you’re looking for an affordable, effective way to upgrade your dental care at home, this is definitely worth it. Highly recommend! ⭐⭐⭐⭐⭐

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.
