I bought the lanyard, cardholder and clip.
1. Lanyard. It is functional although given the price and the nice engineering of the magnetic connection, the loop and button to hold the cable is a bit clunky. The cable is quite stiff so if you wrap it up to store it in a pocket for example it holds the shape a bit or may be kinked. I have not used the USB feature ... may be useful, I don't know. Of course, you may need an adapter to plug it in. As noted below, the connection to the cardholder is surprisingly crude.
2. Clip. I bought the clip because I thought that the instructions said you needed it. In fact, you do not need it to attach the cardholder. I could use it on its own, but as a review of the clip notes, it is quite bulky so does not easily fit on a belt, and if you do use it that way, you have to remove the cardholder to use it - it does not have a cable, nor can it rotate while on the clip. It would not fit under an internal loop in my backpack.
3. Cardholder. Again, going back to the engineering, the cardholder is connected to the lanyard in a slightly crude way. There is a loop which goes through a whole in the back of the cardolder - but the way it is constructed means that the top card holder on the back does not lie flat, and it causes the whole to twist a little.
