After the less good experiences with three, sometimes more expensive manicure / pedicure sets other brands, me Maniquick MQ has 231 very pleasantly surprised. The operation of the device and changing the accessory elements are very simple. The designers have succeeded in both the functional design of the 3 control buttons and their arrangement a direct hit. The buttons are located exactly where the thumb when working with the device. This allows a comfortable calling all functions solely by hand, which also runs the device. The functions off / on, faster / slower and right / left rotation are called quite simply. The NetztgerÃĪt is just insert and done - it must not be further adjusted. At work the MQ developed 231 enough strength for processing also stubborn cornea. However, it is not too strong, so that injuries are largely ruled by too aggressive sanding. Also, the diameter of the grinding bodies is large enough so that too deep grinding can be avoided. Finally, the included protective plastic part turns out to be a very useful accessory, because it effectively prevents the wide distribution of the nail dust. A successful purchase for me.
