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.

Lasted 11 months, which aint bad for what it is! Wait! there's an UPDATE!!
Gonna give it 4 stars. Got mine 11 months ago almost to the day. Just 2 nights ago, seems like the battery is conking out. Just losing the pressure it once had. Worked GREAT the time it was working, so it was worth the $$ for sure. But now time for a new one. Will shop around and experiment with a different brand. !!UPDATE!! OOPS!! I accidentally hit the mode button! Used it again tonight, and it was back to full power. I guess my big fingers hit the button while I was using it. I don't know why I didn't think to check that for two whole days, but no, this thing's working great! Review back to 5 stars!

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! ⭐⭐⭐⭐⭐

Works great. 10 out of 10
I give this a 10 out of 10. The delivery was quick, and I couldn't wait to use it. It works great. It charged quicker than the 4 hours stated to allow, the light will go off when it is fully charged. If this is your first time using a dental teeth flosser, follow the instructions carefully. It comes with different picks, one with a brush to make sure you get a good cleaning. I had water all over the mirror, LOl! But I got it right, and I absolutely love it. My mouth, gums, and teeth feel like I have been to my dentist. I recommend this item, and for the price won't break the bank.

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.
