MacBook Pro Early 2011

I'm about to buy an early 2011 edition 13.3" MacBook Pro in good condition for 500€ used and I was wondering if it is worth it at the price point and the fact that it's used.

Quick specs - 4 GB 1600 MHz DDR3 - Intel HD Graphics 3000 384 MB - 2.3GHz dual-core Intel Core i5 processor with 3MB shared
