Pros: They run at the advertised speeds with default timings and voltage without issue. They were Memtest86+ error-free and Prime95 stable for a full 24 hours. The heat spreaders aren't just for show as they actually do seem to make a difference in temperatures. They're gorgeous and have a nice heft to them; very solid.

Cons: As of now, none.

Overall Review: Some people would argue that 2400 MHz is pointless, but hey, if your motherboard/CPU can handle it and they're don't cost too much more, why not? --- Full system specs (all stock): CM Storm Trooper Asus Crosshair V Formula-Z (1701) AMD FX-9370 Corsair H110 G.Skill Trident X 16 GB DDR3-2400 Samsung 840 Pro 256GB WD Black Series 1TB Sapphire Radeon R9 290 Lite-On Blu-Ray Burner Cooler Master V1000 Other: Logitech Z623 Sennheiser HD 280 Pro Ducky Shine 3 Cherry MX Brown TKL (red LEDs) Roccat Kone XTD SteelSeries QcK
