"This product works as it's advertised by helping to remove the sticky plaque and tartar off your teeth that are trapped under the biofilm. The handy pick and mirror help with those hard to reach places, along with the fact that it is rechargeable instead of battery powered is a plus. I believe to obtain the best results with this scaler, it should be part of your basic oral care routine as nothing is better than a multistage approach. The packaging was also in impeccable condition which is a plus as you can evidently tell it hasn't been tampered with"
