Looks like a decent unit, but mine arrive defective
I drink a lot of coffee and tea so there is discoloration on my teeth. Not to mention regular plaque build-up.<br /><br />I was excited to get and try this sonic cleaner, but I never got a chance to try it because it didn't work. The item I received was dead on arrival. I charged it for 3-4hrs on different chargers and the unit would power on, but the sonic cleaning was non-existent.  It did not work when making contact.
