Pros: Item is well constructed and works right out of the box. Installed two into an 8 server rack, connected equipment, and powered up. Everything worked fine. Servers supported /protected by APC SmartUPS 2200.

Cons: One unit failed November 28 during midnight routine backup, which represents a medium load for this time of year. Item failed 46 minutes into job.

Overall Review: Item shipped to manufacturer last Friday, they should receive it this Friday. I will let you know what they determine.

Pros: Item arrived exactly as advertised. What a great deal, two for 172. Expanding our small company and these worked out just fine. Very happy.

Cons: None

Overall Review: Grab yourself a pair.
