Thanks for raising it, Hidari.
This is a good place to mention to everybody that MR does not actually endorse any of the products or services that are advertised. In my opinion there are some excellent things, plus some that are debatably useful. So, if you decide to click on an advert, then use your common sense to evaluate whether the product or service is really what you want. You could usefully search this site (and the web) for product reviews before making purchasing decisions.
