I've bought Carrera 2607 ultrasonic cleaner for domestic use, for mainly clean my jewelry so. I am of the performance of the device very surprised and pleased. The best cleaning can be achieved with hot / not hot water and Corregatabs / cleaning Tabel tablets for dentures, this I solve previously on in a vessel and then pour the contents into the ultrasonic cleaner, then the jewelry with clean water and dry with a microfiber cloth. The cleaning process in the device should be repeated depending on how dirty, with me the jewelry was to 2x 5 minutes I sauber.Da in working the ultrasonic cleaner Sonorex (very good) am used to, you can then of course the Carrera 2607 not compare. Give still the note 2 to the Carrera 2607 price / quality OK!
