I read the last three pages and was very disappointed in what people write. All unhappy with the all need on different. It's so easy to sit in your chairs and judge someone else's work. Please show respect to the man, he made a successful project and working on it, he even found it necessary to know your opinion about exchanges, and the fact that some number of people do not agree with the majority, does not mean that you are trying to deceive, well, I do not see sense now to use conventional exchangers.

remember patience is a virtue.
