Used about a dozen times. Was going to use it for a business project that got cancelled.
It can produce a range of colours depending on the settings. I used it on a 4 inch square of
titanium plate and created an interesting design. Very easy to learn and lots of fun.
Anything that's titanium can be anodized even if it already has a colour. You can turn a single
coloured object into multicoloured. It can also do silver so you can buy old jewellery and make
it look new or just more interesting.
