COSLUS Skilled Water Flosser & Electrical Toothbrush Combo for Enamel, Braces, Gums Care – Easy & Straightforward to Use, Rechargeable, Waterproof, Cordless & Transportable for Journey, BPA-Free, Black, C20 & C41

Great product
I recently got braces & was sent a link with a number of products that they recommend & this was one of them! I had a water flosser already but it only has 1 setting on it & only came with 2 nozzles. This water flosser is amazing on my teeth I love that it has different settings the soft setting is perfect!! & the toothbrush gets a 10/10 ⭐️ it reaches alll areas of the moth & has a few different settings. Between them both it comes with many different nozzles!!

Awesome product
Sturdy product, comes with plenty of extra brushes and floss tips. Makes it fell like i just left the dentist!!

Great job of cleaning & flossing
Does an excellent job of cleaning and flossing. Takes some adjustments to water flossing, so the back spray from the teeth does not spray back on the bathroom counter and mirror. The timer feature is awesome to ensure proper brushing is accomplished in each area of the mouth.

An effective dental hygene set of somewhat uneven quality
[1] This is a dental set of an electric sonic toothbrush and a water flosser, claimed on its box to be made by the Xiantao Yimaiju Trading Co., Ltd. — this, however, seems unlikely because Yimaju is a trading and not manufacturing Chinese company. It is sourced by Shenzhen Bichengyisi Technology Co., Ltd. (China) and sold here via its storefront, under the Colsus trademark (though the logo of the registered Colsus mark is different from the logo of this set). Neither device comes with a power charger. They are claimed to have a lifespan of “over 3 years”. Although the set only became available in 9/2024, the third figure from the top of the webpage claims at the time of this writing that “2 in 1 Dombno US dental professionals recommend” it. I wonder what “Dombno” means and why the dentist in the figure wears a stethoscope (!) around his neck. [Update — after this review was published, Dombno was changed to Combo, and the stethoscope replaced by a denture.] [2] The rechargeable toothbrush is the model C41, which is missing from the Colsus store products (but is listed in some other brands, likely from the same OEM manufacturer). At the time of this writing, the vibrations per minute [VPM] of the brush are not disclosed. This suggests that it has a comparatively low vibration frequency, since VPM is one of the main commercial advertising points for sonic toothbrushes. At any rate, it is indeed a sonic toothbrush (as opposed to an ultrasonic one) as its audible vibration is below the ~20 kHz limit of audible frequency of human range, so it relies on side-to-side vibration alone to clean the teeth. The toothbrush does not have a standing base, and inherently has poor contact stability when standing up on its own. When fully charged, it is described as usable for up to 45 days in its “clean” mode setting. It lacks an antislip design, and it is difficult to achieve a good grip (which can help clean the teeth more effectively) when wet. It does not have a pressure sensor. The bristles have an oval (as opposed to diamond-shape) arrangement, and they are cut in a W-shape. Compared to similar devices listed on the main Chinese wholesale platform, this seems a low(ish)-end device. [3] The rechargeable water flosser is the model C20 oral irrigator, which is also sold alone on Amazon (search “ASIN: B0BG52SJ5N”), where it received under 80% of positive written reviews out of a total of about 8K as of 10/2022 at least. Many studies report that water flossers remove biofilm from tooth surfaces, and bacteria from periodontal pockets better than string flossing. A water flosser is especially helpful to those for whom string flossing is difficult due to dexterity problems. When fully charged (which takes around 3 hours if the LiPo battery is depleted), it is described to be usable for up to 30 days in its “clean” mode setting. The BPA-free water reservoir is fully detachable. Flossing with a 1:1 mixture of an antiseptic mouthwash and (warm) water ought to be beneficial for its germicidal effect not only on the gingival bacteria, but also on the bacterial colonization in the flosser’s nozzle (reported in an EU-multicentre study of 2023). Rinse the reservoir after use. [4] At the time of this writing, its cost (with the current $10 discount coupon) places it in the low end of the price range on this platform for this kind of set. ~~
