I paired this with a Logitech G403 mouse and G533 wireless headset and Ive zero complains so far. Its a rectangle, it has a knob and some lights, and I really dont mind at all. With the exception of the cord length which is a plus, this charger performs exactly like the one I am replacing. 5, and I bought 9. The insole is only a couple milimeters thick, so I dont think Im going to be missing out on any cushioning. Fits all my shoes perfectly. For the set I received, there was an additional "con" of one of the two sticks not functioning, but Amazon took it back and refunded my payment quickly and painlessly so no stars removed for that. The shoes go with everything and the color is the main attraction. I did size down from my Gizehs (I did a a 38 for my Madrids, have a 39 for my Gizehs). I purchased those dinky thin metal bars with PLASTIC connectors and it definitely broke.
