Avoid avoid avoid! Looks like a $40 off-brand keyboard. Then the left one quit working. I read both the reviews available before I decided to buy this item. I did go to a Foot Dr at Kaiser. but not both. If you are looking for the best portable power bank for your devices at a great price, it does not get any better. So I accept it and move on. I installed these and at first I thought they were wonderful. These kill my my ears after wearing for any length of time.
