I received my NanoVNA yesterday. I purchased from this ebay seller: Took about 3 weeks to receive the unit. A friend of mine ordered from the same seller and he got his in less than 2 weeks (he only lives about 50 miles from me) so shipping time varies.
Seems to work fine, as many have mentioned, the toggle switch is not the best but it does work OK. Here's a few pictures of the packaging and NanoVNA I received.
