this review title is: toy not a tool also deceptive product description and the content is: absolutely terrible read the description carefully all the lists of accessories are for a kit which this is not reviews all show a kit so it appears the seller has switched the product to an inferior item after getting good reviews for a larger kit with a different handpiece many of the shanks are not which requires a collet change and half the time i couldn t even get the spindle lock to work very underpowered and the grinding burrs are dull a worn out nail file is more effective sending it back.there are other information for this review, one is this reviewer did purchase it and the other is 12 people think this review is helpful.
