This tool is amazing!
My bottom teeth are somewhat crowded so it is very prone to staining. I am always embarrassed about the staining and don't really know what to do between dentist visits so ended up ordering it after reading through the reviews. I must say this is absolutely worth every single penny. I ended up using it as soon as it arrived and used it on the second lowest speed. Took me just a couple of minutes to get the stains off!
