Legit Reviews says these kits are rumored to be rebrands of G.Skill memory and notes these kits offer just three years of warranty, whereas most brands offer lifetime warranty these days. EVGA responds the short warranty is the result of keeping inline with their other products, which also have a 3 year warranty period.
When it comes to pricing it looks like EVGA is being fairly competitive. Take the EVGA 16GB (2x8GB) 2133MHz DDR3 memory kit for example. It runs $109.99 plus tax or shipping and has CL11 timings (11-11-11-30) and runs at 1.5 Volts. The Corsair Vengeance Pro 16GB (2x8GB) 2133MHz DDR3 memory kit runs $139.99 with a lifetime warranty and has similar 11-11-11-27 timings at 1.5V. The cheapest priced 16GB dual-channel 2133MHz kit on Newegg would be the G.Skill Sniper Series at $99.99 shipped with 10-12-12-31 timings at 1.6V and a lifetime warranty.
