What could have been a good deal, considering the performance and price are, n 'has not been in my case, I have a drill dozens of holes in the wood and my drill that is stopped , I have previously found that the button did not respond directly when I 'leaned, but now nothing, nothing, either as regards the guarantee, the email address provided no response, despite several letters, that is why I puts a bad grade and now I would stain to stop buying this brand and especially abroad.
