Who buys a H1, has certainly uch a USB cable, so I do not think it necessary. The hand holder need not, because you can hold the device with the same tripod (which I have not done yet). One can argue with the pop protection, I do not need him.
Really bad is the processing of the stand. I have much in use. Unfortunately, a foot broke at the first or second use. This is done simply cheap.
I would have also found useful if the tripod still could be attached to the bag, so that you both have together hand.
