Comments: This is working great, and installed in less than 5 minutes. I ordered the memory on 6/21 and to my surprise, it got delivered the next day. Your awsome newegg!

Pros: 16MB read and 13MB write times started out great. Price for 16GB card Newegg customer service is great

Cons: Wintec brand is questionable. Read and write times diminish over time.

Overall Review: When I got my 1st card. The read and write times were great. But after a few weeks those times started to diminish below the stated class 10 rating. Newegg was more than happy to RMA the card and send me a replacement. I would give Newegg a five rating alone for their customer service. So here I am with the 2nd card, and read time is 13MB and write time averages about 9-10MBs. I am going to constantly test the card. And I will post back in 2-3 weeks. Also FYI. I used Crystal disk mark and H2testw 1.4 with my laptops built in card reader for testing purposes. And both pretty much yield the same results.
