Hi All...

Recently, I purchased several pair of chips on eBay. I always test them. Here is what I found...

In Pic1 is a Sandisk Counterfeit Extreme Pro 64GB U3. Came out of the Midwest...  

The serial number on the back of the chips are: MMB3D08BUACA-GE.

   As you buy on line, don't buy if the back type resembles these numbers and their format. In a test, they locked up my Mavic within 30 feet of the takeoff point... More digging revealed the following test results with Speedoff:

Pic2 is worse. In Pic1 is a Samsung Pro+ 128 GB U3. Came out of PA. There are 5 separate listings on eBay...  

The serial number on the back of the chips are: MMSCGS8SJRSS-TB. Speedcheck is slower than the other one. Also locked up Mavic and Inspire...  Inside tests.

   As you buy on line, don't buy if the back type resembles these numbers and their format.

Both sellers were informed and refunded me. Probably a bogus wholesaler sold to them.

I'd never buy off of Ebay in the first place. Too much of a risk. I'm getting cards @ £7.50 each from a reputable store anyway.

I buy Integral Memory cards direct from them. Use multiple different spec cards and sizes. Touch wood, zero issues so far. Use in cam corders, 4K Action cam, digital cameras DSLRs, drones, CCTV cameras, etc etc. Truth be told, i wouldn't purchase off eBay. Take a guess that 4 out of 5 cards are likely to be fake.
