You are quite right, Dave, everyone does have a right to their own opinions. However, it seems to me that if someone expresses an opinion that does not coincide with yours, you immediately shoot them down. I am not disputing the fact that you have had experience of the ESCs in question failing, at least one spectacularly, I am merely telling of my experience with them which, so far, has been good.
The sum total of my knowledge of electronics could be written on a 1p coin with a broad tipped felt pen, so I would not dream of arguing with anyone who has knowledge of the "Black Art". I would also encourage people to take note of acknowledged electronics experts such as Dave Milbourn, and others, whose advice should be listened to carefully when wiring a model boat.
