Thank you, I didn't notice the promo code shopping slightly drunk. It worked, $3.99 with code. This is a good brush to leave behind in a hotel accidentally.

Thanks, OP. This Coslus electric toothbrush has been on Sale since Oct'25 starting from $10, then in Dec'25 went down to $7, then $6 around Christmas, then $4.80 in Week-3 Jan'26, and then $3.99 starting in Week-4 Jan'26 with numerous Promo Codes. I think they did these Sales to make them the Best Seller on Amazon and they actually are (or once were) the Best Seller. Just my 2-cents. Wink

IME even a cheap electric like this is noticeably way better than manual brushing. Better job in less time.

I bought one of the cheap electric brushes similar to this before. It's pretty weak. At this price I'm assuming this is the same. Probably better for kids but for adults, it's better to pay a little more and get a stronger/better one.

I like their water flossers, and bought one of these to try as a travel brush (easier to pack since it doesn't need a charging base like my Sonicare does). Thanks OP!

I have this one. My last cheap one from Amazon lasted almost 2 years and my dentist gave me an A+ for brushing. So I replaced with another cheap one recently and it failed after about a month. Amazon gave me a credit and I bought this one for like $7. The brush heads are just the right softness and the strength seems like 30k to 40k although not provided on box. There is a 2 year warranty which says something about quality. I'm using this as a spare and replacement heads.
