I was skeptical when I first bought it. It was on 80% sales so why not. But it works. I noticed my teeth was better when using this toothbrush.

I never use any thing else but this I love it

I'm a toothbrush connoisseurs. Love to try different brushes on the market. I've tried softer and smaller tooth brushes. Not the worst, but a little harder than most soft toothbrushes. Made my gum bleed so I threw it out after like two uses. Better toothbush pictured below...

very ordinary brush 
 

I love this toothbrush. It cleans real well. The shape seems to work better with my teeth and I notice a difference to how white my teeth is compared to my old brush. 

Tooth brushes with this shape are becoming really poplar online so i was glad to find this one, it really cleans very well with the tapered bristles, teeth feel cleaner with this medicube brush than a regular toothbrush, did not expect that.
