Vendor said "delivery in 30-35 days". It arrived on day 88 of the 90 day guarantee. It was returned to the vendor twice & reshipped *twice*, possibly due to issues with export or maybe the included LiIon battery. It arrived opened & with firmware that didn't boot . It was confirmed by SiPeed to require refreshing, which cured the product. Before they kept reshipping it, I asked for a refund as during that time, it had become available (for $39USD instead of $55USD) and shipped from within the US. Not acceptable to vendor. They shipped the product to me three times, with only the last succeeding. I''m fairly happy with the product. The doc is atrocious, but I'm working with SiPeed on that. Despite my frustration with the shipping delays for this vendor, they were the only one of five I ordered the day that got products out of China before the 90 days expired. My commitment to honoring this purchase ultimately cost me probably 75 days of delay and an additional 40% above MSRP.

Untested, but appears new & in perfect condition. Will update review if have quality/performance issues. Very satisfied with purchase and highly recommend Product and Seller.
