Nope, I don't want that. Method does not relates to the idea you have mentioned. Although, seems like a nice alternative if it really works so thank you for it.
My method is nothing like that. Furthermore, I said that with a bit of tweaking you can get keys that last longer than a month.
If you find the method stupid, expensive or whatever else just skip it. Look for some other alternative and buy them somewhere else. I am ok with that.
For anyone else that is interested offer stays available.
