Student loan consolitation

[steelcmg]

I finished college last year and owe about 17K in loans. I keep getting things from a company called Nelnet to consolidate my loans and save like 2% on intrest. I remeber hearing to stay away from doing this but i dont remember where i heard it from. Are this things worth looking into or should i just stick with paying AES. My intrest rate with AES is like 5%
