Doesn't work
I bought this item during Prime Days since it was such a good price.  I did not read the reviews.  I wish I had.  When I opened the box, the item had scratches on it as it if had been used and returned already.  Plugged up the gun and let it charge for hours.  it never powered on.  I feel the seller sent me a defective item.  Returning today.
