Excellent Brand
I have been using this COSLUS electric toothbrush for theee months now and I’m genuinely impressed with what you get for the price. Best of all when you register the product you get a two-year warranty. First off, the cleaning performance is solid. It has a strong sonic vibration that leaves my teeth feeling smooth and clean, comparable to other higher end electric toothbrushes I have purchased in the past. It’s noticeably more effective than manual brushing, especially around the gumline. The battery life is another BIG win. I only charged it every 3-4 weeks. For travel or everyday use, that’s really convenient. It also comes with multiple brushing modes, which is nice to have depending on whether you want a deeper clean or something more gentle for sensitive gums. The build feels lightweight but not cheap and it’s easy to hold even when wet. The included 6 brush heads are a good bonus and they seem easy enough to replace when needed. Charging is simple with the included base and everything feels straightforward with no complicated setup or app required. If I had one minor complaint, it’s that it doesn’t have the “smart” features or premium feel of much more expensive brands like Sonicare or Oral-B. But honestly, at this price point, that’s expected and not a dealbreaker for me. Overall, If you are looking for an affordable electric toothbrush that does the job well without unnecessary extras, this is a great pick. It’s an excellent balance of performance and value and with a two-year warranty, why not?

First impressions matter—and COSLUS (BLACK) delivers!
This sonic toothbrush arrived in a sleek, well-designed travel case that immediately stood out. The case holds two brush heads (one for current use and one individually wrapped spare), and what really impressed me is the built-in ventilation. If you’re someone who brushes in the shower (🙋🏽♀️), this detail is huge. Bonus: the toothbrush itself is fully waterproof, so no concerns there. The toothbrush is lightweight, slim, and comfortable to hold, making it feel more premium than bulkier electric brushes I’ve used. It features a 2-minute smart timer with 30-second quadrant pauses, which helps ensure even cleaning throughout the mouth. One feature I genuinely appreciate: if you stop mid-cycle—say, to sign for a delivery—the brush resumes exactly where you left off when you turn it back on. That level of thoughtful design doesn’t go unnoticed. There are 5 distinct cleaning modes, and with each mode change there is a noticeable change in brushing pattern, particularly through the blue bristles and angled top bristles. The toothbrush overall is well designed and aligns comfortably with both teeth and gums, providing a thorough yet gentle clean. The brush head shape feels intentional, not generic. COSLUS includes 6 brush heads, which equals approximately 18 months of use based on the recommended 3-month replacement schedule—an excellent value and a big plus for long-term ownership. I’ve only just started using this toothbrush, so I can’t yet speak to battery longevity or how the blue indicator bristles fade over time. That said, I’ll be more than happy to provide an update after extended use. Overall, this toothbrush checks all the boxes: smart design, strong performance, thoughtful features, and great value. I’m excited to continue using it and would absolutely recommend it to anyone looking to upgrade their oral care routine. Great value and works WELL!

Great value for the price
I don’t often leave reviews; however, this toothbrush works so well I am compelled to. I’ve had the more expensive brand tooth brushes and this works as well or better for much less money. Quite, good battery life solid brushes.

Nice toothbrush
I bought this for myself and fell in love immediately. The sonic vibration is no joke — my teeth feel genuinely clean after every use, not just brushed. There’s a difference and this toothbrush makes you feel it every single time. But let me tell you what really sold me. The bristles are soft. Like genuinely soft, not that medium-firm nonsense that has you questioning your enamel after every brush. Soft bristles AND somehow getting my teeth cleaner than any toothbrush I have ever used in my life. I don’t know how they pulled that off but they did and my mouth has never been happier. The multiple brushing modes are actually useful too — not just gimmicks. Polishing, whitening, clean — I rotate through them depending on what my teeth need that day and the difference is noticeable. BUT HERE is the real testimony. My fiancé has an Oral-B electric toothbrush. A NICE one. The kind that costs real money and comes with the fancy charging dock and all that. You know what he’s been using instead? This one. Every single day. Voluntarily. He put his Oral-B DOWN and has not looked back. That is not a small thing. That is a man admitting something works better than what he already had. That’s the whole review right there. For less than $15 this toothbrush is overdelivering at this price point by a MILE. Chef’s kiss doesn’t even cover it. And the multiple extra brush heads included means you’re not running back to Amazon every few months desperately searching for compatible replacements. Everything you need is in the box. Dentist visit about to be boring in the best way possible. Get this for yourself. Get it for whoever you live with. You’re welcome in advance.

Great brush
I have been using this toothbrush for a few days now and it works great my mouth and teeth feel cleaner than my old Oral B electric. I would just like to find how to get replacement heads after the 6 That came with the brush wear out. Great buy especially for the cost…

Clean teeth
This is one of the best electric toothbrushes I’ve ever purchased. I’ve tried the more costly name brands and this one is better. Leta talk about the battery, this battery lasts so long that I will charge it after a few months just to make sure it’s ready for the next use. If you are looking for an affordable electric toothbrush and this is the one and it’s easy to get replacement heads.

Powerful, does the job
This is my 1st experience with vibrating toothbrush. Lemne tell you it's powerful. I have to keep mine on the soft setting. It tickled the gell outta me tikl I figured out leaving my mouth opened was the way to go. My teeth feel super clean after I use this. I love that it came with so many heads and the fact that you can order more later on when needed. I split the heads between my son and i so could try it out. I love that it comes with a case to store both ut and the brush head in. My son just uses a toothbrush cover from walmart since hes testing it out. Id definitely suggest using this. If at 1st you dont like ut give it more time to see if you can figure out a setting that worked better. If youre planning on getting this for a younger child have them test it out with one of the extra heads like I did with my teenager. It may be too strong for the littlest ones. My overall review is a 10/10 There is a bit of a learning curve, its powerful so it may not be for everyone if you have sensative teeth, comes with storage, charging cord and extra brush heads.
