Well, don't count on it.
I've ordered mine 2 weeks ago, got an order confirmation and after that, total silence.
They don't reply on emails, ignore DM on Twitter, etc.
Too bad I live in The Netherlands, no way to pay them a visit..
So in my case Piperwallet is a complete scam and I simply lost 0.2664 BTC..
[edit]
awkward.. within an hour after posting this message I got a shipping confirmation.
I will let you guys know if I really receive the device.
[/edit]
When did they say they were aiming for dispatch?
Well, the shipping confirmation is probably fake as well, a week later, it still says 'PRE-SHIPMENT' on the USPS website.
The piperwallet.com website still states that the device ships within 7 days after ordering.
So people, don't buy the Piperwallet as it seems to be a complete scam.
