I do have proper tools, but didn't have proper chips :( But from experience it should work even tough I had to bend those chip legs a bit to get them soldered.

Yea I understand these are sold to end user and by no means would I encourage people to do this kind of job with no soldering skill or for people who solder rarely.

Oh btw what do you think is wrong with that soldering other than the fact that the chip legs were bend? Everything has a fine contact and solder joints are clean (no cold joints).
