I have just read the earlier thread dedicated to this subject -- and the sometimes ridiculous postings on that thread that deserved to be closed. I have just ordered my first 2 WA chips to try them out. I would like to hear from those who have actually tried them to get an idea about the placement and the results. I am not interested in hearing from anyone who has not tried them. So, I would ask the moderator to delete all posts from those who have not actually used the WA chips. Let's keep this thread simple and informative -- and under control.
