Pros: I have bought TDK on many occasions and they always work just great. I burn lots of DVD's and seldom ever have a coaster. They are also great for data as well. The Black Friday price tag was even a better reason to buy them. Thanks Newegg for always coming through.

Cons: Nothing that I can find about them.

Pros: It works but not sure for how long.

Cons: Cannot Register For Lifetime Warranty. Have attempted to register this product for a week and on their website this flash drive will not register and contacting Adata is useless. They respond by email saying that product registration can be done by sending them photos of the product and the receipt. Tried that but all emails bounce back to me. I have tried various email addresses and they either bounce back from China or the USA address bounce back showing their inbox is full. If your buying thinking it comes with a warranty think again. Your on your own when buy ADATA products.

Overall Review: I'll never buy another ADATA product cause now I'm aware that since you cannot use their warranties then your on your own from the start.

Pros: These are the best deal in town. I use them mainly for data storage and they work flawlessly. The price compared to other brands cannot be beat. I am very happy with my purchase.

Cons: As others have said they are slow to write which is okay with me.
