I ordered 1 at first to see how they were.  It worked sufficiently for my needs so I ordered 3 more for the kids. Unfortunately 2 of the units came without the USB adapter piece for the charger.  This is super frustrating when you have 4 kids trying to charge at night.  I have contacted the seller and have not heard back yet. Will update if/when I do.*Update*Sellers reached out to resolve the issue right away.  No complaints on my end.
