Pros: None.

Cons: The program could not back up my system. Mediocre user interface. Lousy documentation. But the real winner: When I contacted Acronis for support (within the "free" 30-day support window), I was told that this product is obsolete. A complete waste of money.

Overall Review: The Acronis support rep was terrible. While the product got good reviews, I would not consider any product from this company.

Pros: Low price. Metal connectors seem more robust.

Cons: When used with my Samsung Galaxy J3eV phone, the 6-foot and 10-foot cables only worked as charging cables; I could not transfer data between my desktop computers and the phone. (Tried two different desktops, so it's unlikely it's a problem with the desktop's USB port.) With the 1-foot and 3-foot cables, the data connection worked. With the 6-foot cables, the phone saw the potential for a data connection, but the desktop could not establish a data connection and reported an invalid device. With the 10-foot cable, the phone would charge but didn't give me the option of trying to establish a data connection.

Overall Review: The package was supposed to have three 3-foot and one 6-foot cable; I received two 3-foot and two 6-foot.

Pros: The backlighting is nicely done.

Cons: I don't like it. I type a lot and switching keyboards always causes some awkwardness. But that usually goes away in a few minutes or a couple of hours. I've been using this keyboard for hours every day -- and it's just as awkward now as when I first used it. And I'm not sure why. The keys have flat tops; I'm used to sculpted tops. The pressure needed to type is just a bit off -- but enough to make it harder to type. And there are subtle layout differences that mean I continue to get the wrong key unless I look down at the keyboard. There are times I need to type in the dark, so I'll put this one back in the box and only drag it out when I need that feature. But I will wish I not had bought it in the first place. If you need a backlit keyboard, I suggest you keep looking.
