I see someone else has fallen foul of Shenzhen Gusong InfoTech Ltd.
Yes, I also followed a Facebook ad. Silly me! The ad offered a 3/8 drive battery ratchet for around $32US, delivered. Payment via PayPal seemed safe. Item described as a "ELECTRIC WRENCH 3/8" CORDLESS RATCHET" with full tracking and shipping insurance. After several weeks, I received a 4" adjustable spanner/wrench (a "shifter" as they are called in Australia) and one that could be purchased for $2 at the local bargain shop.
After placing the order, I felt a little suspicious so I emailed the seller asking that they confirm I was receiving a battery ratchet. They responded with the old "many happy customers, etc" so I replied to that email asking that they confirm what I was receiving or cancel the order. I've never heard from them again. I have opened a PayPal dispute.
This is the second time I have been ripped off in as many weeks via Facebook ads. At least the other one is communicating with me and I may get a refund. Bottom line: if it looks too good to be true, even with PayPal payment, forget it!
