yes, i got this product in time, fast delivery & i think the sellers are reliable in that matter. however, i bougth the wrong item. My computer doesn't accept 512mb sdram module, it accept two of 256 mb sdram to reach the maximum of 512mb memory Ram. so the problem is this product is not eligible for return, i think, because i ask them for return authorization and they didn't give me one. I guess i just have to save this for future use.
