Product is ok, but the packaging was "oh dear"

Now comes the "but."

When I got the delivery of Amazon, I already suspected the worst.
The part was delivered in a cardboard envelope A4.
This was so tight, that is this sensitive plastic part bent and broken in transit.
Thus, I have sent it by return mail back to Amazon.

I do not blame the seller, the can not help for transportation.
That is why I give the product 5 stars.

I have already sent a packaging review on Amazon, there really needs to be touched up here.

I try it then again with a new order, let's see if it has brought what.
