I am more than satisfied. Together with the Vitadent denture cleaner after 2 days really visible results. Even stubborn evidence that not went off despite intensive cleaning and various tabs that are slowly disappearing. However, I recommend the prosthesis after use rinse the cleaner well, because the taste is not delicious :))) Had tried various ultrasonic cleaner, but for the third of this is so far the best. But beware to all who want to also clean glasses - do not fit into this device. It's just a small specialist for denture. Hope that the durability of the device is not as bad as criticized by some previous speakers. So far, in any case completely satisfied with a beaming smile again :))))
