Great SO-ARM101 seller!
I ordered two back ordered items which I was excited to receive. I checked the site one day and the items were listed as “in stock”, but I had received no information about my backorders being filled. I was concerned that Seeed may have forgotten about my backorder, so I asked customer service for help. In less than one hour, I received the backorder fill notice, and tracking information. Just a few hours later, Seeed customer service responded saying it was shipped. Very good service!
