I'm giving him a negative feedback coz:

1) he sold me the wrong item, he advertised a kingston 1gb ddr333, but was actually only a 512Mb ddr333,it was even marked on the tag (didn't see it coz i just had it picked up and it was in a heatspreader)
2) warranty issue.
2a)m based in caloocan, he's at ortigas. after i informed him of the mistake he made, he demanded i come to him to check the item. the reason i had it picked up in the first place is coz i'm so far away.
2b)he said that he wasn't gonna be available the next day so i didn't have a choice but find a way to go to him to get my money back, he didn't even offer to meet me halfway or something. after that, i had to come back to the office (caloocan-ortigas-caloocan)

overall, it was an exasperating experience and i wouldn't want to do it again... ever.

tips to buyers: make it a point to test the item before you by, you might end up like me, buying something and having to return it the hard and unpleasant way.
