Very reliable and sleek product
Very useful and better than most of the products which are double than its price.

Good but too soft
It's a good flosser but very gentle. So if you are used to something with more pressure then avoid this. Good for beginners maybe or someone with sensitive teeth and gums.

Not Powerful Enough
The product I received doesn’t have the Coslus branding on as pictured in the listing. I previously owned one branded Coslus, and it was great; super powerful, perfect amount of water in the tank and the battery lasted forever. This one looked slightly different so I just assumed it was a newer model. This is some poor weak version, I can still feel things between my teeth after I’ve used it. It’s really not powerful at all - I’ve seen reviews mention that the pressure pops the spout off - I don’t know how, there’s no oomph in this, at all. Threw the box away as I received it in the afternoon and didn’t use it until the evening, so don’t imagine I’ll be returning them - they’re probably suitable for children but the previous model I had was so much more powerful - therefore I’ll be looking for an alternative brand.

Doesn't work as a water flosser
While it does try to floss, it's just not strong enough to clean anything. The water capacity is also not large at all. It's medium at best and gets empty really fast. It's cheap, and the price is tempting, but it just doesn't work.

Broke in 2 Days – Water Leaking Everywhere!
This product is absolute junk. After just 2 days of use, it started spraying water out from the nozzle base instead of working properly. The quality is terrible, clearly very poorly made, and it feels like a waste of money. Totally unreliable and not worth buying. I would never recommend this item to anyone.

Poor quality product without warranty
The product stopped working within 2 months. I tried to recharge it, but without success. I checked with Amazon, and they informed me that there is no warranty on this product.

So happy with this purchase. It is handheld, not noisy, and my teeth and gums look and feel clean.

Works very well! Please make sure you follow use instructions, especially about how to get your gums to adjust! It can be powerful and you don't want to hurt your gums.

I needed I but I was thinning for long time. It’s little bit difficult to use it couple times but it’s ok.

It does the job!! The pressure is good! I love the pink color. I accidentally bought another charger becuase I thought it didn’t came with one😭

Given the price, you really can't expect anything more. It does exactly what it's supposed to do, and even if it doesn't last very long—at the cost of just a single previous Oral-B device—I could buy several of these. I also really appreciate that it's a portable product that I can easily take along with me when traveling. Good quality at a reasonable price.
