I ordered these as Christmas presents for my kids and they arrived to New Zealand very quickly, I had a tracking number within a couple of days of ordering.
They haven't been put together yet (it's not Xmas yet) but everything is there and I'm happy with the kit. Looks to be very easy to put together.
Only thing is I would have preferred the instructions to be sent with the kit printed. But it's not a big deal as they are available for download on the product page. I'll just print them off myself.
Ultimately I will be happy to purchase again from smalldevices as they have a good range of kits and they ship quickly.
