I have used this item for several months.  The thing I noticed when I first received it was that the tip of the plug did not seem to fit firmly into my Nexus 7 tablet.  I was a little concerned because my OEM cable tip bent causing the need for the replacement.  So far no problems with that also it does seem like a loose connection.  My main problem is that the tablet will not fully recharge even overnight using this cable.  I now use my charger and cable that came with my phone which fully recharges the nearly exhausted battery (20-30%) in less than two hours. IT works great.  This replacement cable did not work for me.
