I put 4 just because the strip is bulky or we sense that the materials are of quality, the branch is taken gently and removes them without any take with either. The power LED is discreet and I like telling you light the ground :) The cable to the correct length (1.50m) without being too short nor too long ... it's also up to you in your installation if it is enough or not. USB Catches have been one of the selection criteria for my part, I find it very convenient because it avoids having a transformer plug and convicting taken, and seen all that is recharged via USB now it's almost mandatory!
THE biggest problem for me, the decision is very cumbersome because the principle of having USB ports is to be left easily accessible so apparent
I highly recommend this product to a one who needs to charge different devices via USB if other quality outlets are available on the site or of the same brand.
