I think if your wanting to get into off camera flash, these are perfect for you. They are simple and bare-bones. They come with that PW name that we all know and love. At a price tag of $99, how can you go wrong.
If you have PW 2's or 3's, why would you waste your money on them. Unless you need to replace a few trigger, I wouldn't bother. My old PW 2's have been working great for all the years that Ive owned them.
