Some time ago I bought a cheaper pedicure set from another manufacturer. In retrospect, it was out of money. The unit remained at higher pressure are, the instruments are not properly maintained and .... I decided now that Maniquick MQ 251 Professional manicure-pedicure to buy -Set and must say that I have not regretted it. The motor stops even when stronger pressure level and the instruments are secured against rotation. The speed can be adjusted well. The device is supplied in a case with lots of accessories. I would buy the device again.
