Great Product, but installation not obvious
My only complaint about these is that they didn't come with any installation instructions. They are not at all symmetrical, and there are are literally 8 different ways they might be inserted into a wall plate or wall strap. I couldn't easily find any instructions on the internet. Afraid of breaking one trying to insert it incorrectly, I called customer service. They didn't know off hand, but they were able to find something and tell me how to do it. Some unnecessary time and aggravation. Otherwise I would give them 5 stars. Once you know to insert it from the back with the proper orientation, they can be snapped in and removed from the plate with reasonable ease.
Pros: Only one insert needed per speaker. Can provide connections for twice as many speakers in a wall plate or strap with a given number of openings, six speakers max per single plate or strap.
Cons: Not at all obvious how to install the inserts. No installation instructions.
