Unfortunately, my then-mouse Roccat Kone [+], or actually the cable did not fit into the bungee, so I had to adjust the mount something. Worked wonderfully and after this step, the holder liked better.
Much of it but you can not expect what is intended to provide a bungee already, except maintenance: D
But there is just now the problem of the cable holder.
Over time, the grip goes to the desk and the bungee moves in violent mouse movements immediately.
Too bad, but I doubt that it will look different in other products.
Consider me even the holder to buy again, because my current mouse (Roccat Kone XTD) has a thinner cable and so no longer in harmony with the 100% holder)
