I dabe now about 5x had the VeraTip in use, and now the catalyst begins to dissolve. The cat is the small tube in which the tools (eg, tip) is screwed. The screen in the cat is now burned half. Because I thought that thing was a penny article I tried to get over the Dremelservice a replacement. The tube will cost about 15 euros, plus 7.50 euro fee, plus 2,50 Euro shipping and bolder way for about 5 euros order fee for online orders. Power thus together 30 euros for such a small part, the entire device from Amazon will cost about 36 euros - or about 84 percent. Beautiful German Wegwerfgesellschft.
