Before I got this I had wires everywhere. Everyone trying to use the same plug in. This is a life saver. We can now charge as many phones as we want while having a fan plugged in and tv. Also don't need the boxes to plug the phones into anymore this has usb charging. Also it goes 10 feet but rolls back into the device if u want it shorter. I will say the only negative is that I have a cheap phone thru Walmart and it don't work on the wireless charger it does work for iphones and Samsung's and that's what most people have. Using the wireless charging top is easy color instructions so u know if it's working or not. Read all ur instructions to see all the sweet stuff this does.
