If that was my Steam Turbine,I'd be attacking it with drill-bits too only on both sides,then adding a dual-coil setup & only then would I decide whether my £25 was wasted.I know that people expect to get a good device for £25 that requires no alterations,but I see it as like a "off-the-peg" suit versus a tailor-made suit,one is designed to fit the largest range of people and one is for that one person.
