Impressive all round
First of all, the ultrasonic cleaner is excellent and the day after using it I cancelled my £70 hygienist appointment. This will be a big money saver in the long run. Secondly I'd like to compliment Yam on excellent customer service after a small hiccup with another order item. I'm actually going to say that the customer service exceeded my expectations. I highly recommend the products and professionalism of this company.
