Their customer support has also been great. I ordered an early batch, they discovered it had some problems and proactively notified me, explained they were manufacturing replacement batches and then sent me the bug fixed version. And I hadn't yet noticed the problem. How I wish all companies were like that.
I ordered some sugru a year ago, but apparently the shipment got lost in the post. I replied to the order confirmation mail pointing up the delay, and shortly afterwards I got a mail from Jane herself telling they would ship a replacement.
