Well I'm the guy that fixed his two O2's (Both going to others, the one going to ulogin here in the thread) and his gamma2 DAC. While I did get my money, it may have been because I had his DAC and O2's that were built for others. I could not tell you how many times I heard that he needed them shipped by the 16th because he was leaving for Alaska, a very demanding person for someone that seems to be dropping the ball on his end, but here is the gist of it.
I was selling a 2 channel B22 and ulogin purchased the amp from me, and he had mentioned about his O2 and it not working so I said maybe I could fix it (I've built my own and have 20 years of electronics hobbiest experience) and he in turn had Justin contact me, I could tell from the get go that Justin is a very 'nervous' person with many, many PMs. We agreed that I would fix these two O2's for a Fiio E10 in exchange and this is where the fun starts.
He was to ship the items to me and mentioned that he had a Gamma2 that also dose not work, he was in luck that I also have built a Gamma2 and told him I would take a look at it but it would cost more because the Gamma2 was more complex (Surface mount chips, etc) but before we agreed on any price Justin offers a pair of headphones (Don't remember what kind). I replied that I had no interest in another set of phones, but was interested in the E10 with a bit of cash for fixing the three items. He then tells me that he sold the E10 and offers me a pair of headphones (Don't remember the kind), I replied that I had no interest in the headphones. He then offered them again and I replied lets just make it for $85.00, he said OK but it'll be a bit before he can pay, and he shipped the items (With a loan from ulogin, I believe). I received the items (Poorly packed in a cardboard USPS envelope with no padding) and preceded to repair them.
His soldering skills are mediocre at best but I understand someone has to start somewhere but don't sell items that you can't build (O2's are quite easy) I had both of the O2's fixed in one night baring a bad op-amp in one. ulogin's O2 did not work simply from bad soldering and poorly clipped wires, the other had those issues plus a broken pin on an op-amp which I repaired and just a bad op-amp which needed to be replaced (I bought it from mouser with my own money since it was cheap) I was surprised that someone would sell such poor work.
I then took a look at his Gamma2, nothing worked no power at all (There is a lengthy thread on AMBs forum about his Gamma2 and how the soldering is poor, and people trying to help him, etc.) Again very poor soldering and even one of the surface mount chips was just off on it's pads causing many shorts (I admit I though to myself how could someone spend the money to build this and do so poor at it) After removing and fixing some of the surface mount chips, I got power to the board and got most everything working but discovered the DAC chip on one of the boards to not be functioning (most likely from solder bridges that allowed 5V into a 3.3V chip) and told him it needed to be replaced. He somehow had a second chip he sent to me to use but seeing his shipping and fearing that the second chip might be damaged from static discharge I went and ordered my own from Mouser for $10.00
I then preceded to repair his Gamma2 only to discover another bad component. Now all along though this process I kept getting PM's about how he sold this so he could pay me sooner and that I need this all shipped by this day, then telling me I bought this so it'll be delayed, etc. I feared dragging this on to long so I removed the needed component from my own functioning Gamma2 to fix his! With the last component in place his Gamma2 was fully working.
I also noticed that he was trying to drill out a faceplate for his Gamma2 and again saw that he wasn't doing a very good job of it. Having just built a CNC router I offered to make him 2 plexi faceplates for his Gamma2 for an extra $15.00 making a total of $100.00. I made the plates and he asked me to send him pictures of the unit so he could see the plates, which I did.
Then ulogin brought to my attention that he was selling his Gamma2 here on head-fi. I said how can he be I still have it on my desk! (I was actually listening though it to test it) Well, he had used the pictures of the faceplates that I took and used them in his posting for the ad!
He then told me he would be late paying me but asked me if I could ship the items to him, after reading this thread and a couple others at other forums I told him he would need to pay me before I shipped them. He then told me he sold something (don't recall what it was) and he could pay me. In a couple days I had my $100.00 and shipped ulogin's O2 directly to him (Before I was paid , felt bad about all he had been through) since he was afraid he wouldn't get it from Justin before he left for Alaska and shipped the other 2 items to Justin.
That's the gist of my story, I did get paid but it was an interesting ordeal. Justin then asked me a few times to make panels for his O2 ( don't know if one I fixed or not) but I just didn't want to get involved knowing he was leaving soon.
Like I said I got my money so I can't say anything about that but I would be weary of his soldering work if someone was to purchase something from him.
Maybe this will fill in some of the blanks here.
I have to say I really don't like to post about someone doing bad work as I too had to start somewhere but in this case with the lack of payment to others and the fact that he did poor work and then sold it, I have to say something here. I am by no means ripping on his skills, I would hate to have someone do that to me, I'm just informing of the work quality and how things panned out.
