Mannesmann Tap & Die Set 32pcs.

bought these through Amazon as thought they would be good with been German I only used them as hobby and one broke (credit to Amazon they did replace it ) then a few weeks later another broke , amazon say 10yr warranty great if you can read German as the site is in German as one of amzons customer service guys told me , a bit misleading if you need a replace really thought Amazon would have done there homework first so direct contact could be made with the firm as I doubt in 3-5 yrs amazon will be interested in honouring the warranty, it does come in box but they keep falling out of there designated place , they are made of cast and not metal so they do break easy ,
would liked to have known that I had to able to read German on there site
as would not have purchased them
