In Nov. 2017I saw there ad for 3DR solo Gimbals for $138 with free standard shipping. So I ordered two with paypal, about a week later they sent me a email to say that they only had one in stock with more to come, they said they shipped one and would refund my paypay for one (they did). Thinking they were legit in Dec. I ordered three more (this time paying for air). BUT as of today I have received nota. Paypal is trying to make thing right ( I have got a refund for the first one and working on the others.
