Hi Alga, you are quite correct but we live in such a litigious society that you have to put in disclaimers or risk getting sued. It's like MacDonalds having to warn that coffee and hot apple pies might be hot
All it takes is one oaf that decides that rather than working for a living they would try out electrolysis in a very small shed while smoking a pipe, blow themselves up and then sue me for everything I have. Hence the warning
Best and all that,
Dave
