What happened to the Dragonskin Armor?

[Yazp]

"Dragon Skin is a type of ballistic vest formerly made by the now defunct company, Pinnacle Armor which filed Chapter 11 Bankruptcy in 2011. Its characteristic two-inch-wide circular discs overlap like scale armor, creating a flexible vest that allows a good range of motion and is intended to absorb a high number of hits compared with other military body armor. The discs are composed of silicon carbideceramic matrices and laminates, much like the largerceramic plates in other types of bullet resistant vests.

In a test for the History Channel's military show, Mail Call, the vest repelled nine rounds of steel-core ammunition from an AK-47 full automatic and 35 rounds of 9×19mm from aHeckler & Koch MP5A3, all fired into a 10-by-12-inch area on the vest. On Test Lab, also on the History Channel, the vest withstood 120 rounds fired from a Type 56(7.62×39mm) rifle and Heckler & Koch MP5 (9×19mm). In another demonstration on the Discovery Channel series Future Weapons, a Dragon Skin vest withstood numerous rounds (including steel core rounds) from an AK-47, an Heckler & Koch MP5SD, an M4 carbine (5.56×45mm), and a point-blank detonation of an M67 grenade. While the vest was heavily damaged (mainly by the grenade), there was no penetration of the armor."

However, when the US Army tested it, it failed miserably.
Currently, US Secret Service, CIA and the FBI use these vests, with a small amount of Security Contractors...
Look at the US Army's test report:

Also, one of these vests cost 1500 USD a piece! While a Level III AR500 Plate costs ~250 USD
