The plugs simply dont work, a really stupid thing and something you would not expect from a so called pro products, some plugs have a different color coding for the wires, so if you blindly follow the coding on each plug you want to end up with a Death connection. So after you have connected the happily plugs (Which goes pretty easy got to admit) you discover there is no connection and since you thign its all color coded and Its Actually Fool Proof you start looking for reasons. And thats what I did and did what When I discovered the two plugs Which have the same model number have different color coding so yeah very professional.
So you would expect Those plugs to be multi usable but well as soon as you open it and you fix the wiring issue you will notice That it does not close properly anymore.
So all in all Those plugs are worthless and are way to overpriced you better go to your local DIY store and grave Some of the cheap looking CAT6 plugs theywill do the job and with a little bit of ISO-tape They hold wants plus you get 2 for less then thesis plugs.
If you got money like Mr. Gates and you have a ton of spare time buy them for the normal people do not do it and save your money.
