sorry to revive this thread again. this was my chat session with a CS from OWC:
OWC Rebecca: [9:53:33 PM] Hello Adi Chandra Hid.., thanks for contacting OWC Customer Service. This is OWC Rebecca. How may I assist you?
Adi Chandra Hid..: [9:53:33 PM] when is envoy for 2012 11" air is going to be available?
OWC Rebecca: [9:53:58 PM] I am not sure if I have an eta on that. Let me check
Adi Chandra Hid..: [9:54:38 PM] ok
[9:55:23 PM] btw i have a complaint for owc about the build quality of mercury aura flash storage for 2012 air
OWC Rebecca: [9:55:42 PM] I am sorry but I do not have any eta on an enclosure for that drive
Adi Chandra Hid..: [9:56:16 PM] i live in indonesia, and it's like the other side of the earth from US
[9:56:30 PM] and i recently bought a mercury aura 240gb for my 2012 air
OWC Rebecca: [9:56:50 PM] Okay
Adi Chandra Hid..: [9:57:13 PM] the shipping is expensive, it was about $50 and the tax i had to pay for the government here was about $110
[9:57:29 PM] so the total cost was about $460
[9:57:57 PM] when i received the aura pro, it didn't fit on my air
[9:58:28 PM] so shipping it back to owc is not an option because i had to waste more dollars
OWC Rebecca: [9:58:48 PM] You are certain you have the air model 5,1 or 5,2?
Adi Chandra Hid..: [9:59:09 PM] the 2012, i don't know the certain type. it's the new one, custom order with 8GB of ram
OWC Rebecca: [9:59:37 PM] Apple continues to sell the leftover models at the same time. Are you sure?
[9:59:40 PM] What is the serial number?
Adi Chandra Hid..: [9:59:50 PM] hold a sec
[10:00:17 PM] it's a 5,1 with serial number C02HW0VCDRV9
OWC Rebecca: [10:00:30 PM] Okay just checking.
[10:00:37 PM] Have you spoken with techs?
[10:00:47 PM] That drive is only for the 2012 model so it should fit
Adi Chandra Hid..: [10:01:09 PM] no because it's going to be useless. i bought the exact model, the right model for my air
[10:01:19 PM] it was just the build quality of the aura is not good
OWC Rebecca: [10:01:38 PM] We have not had any other complaints from other customers that the drive does not fit.
Adi Chandra Hid..: [10:01:39 PM] i had to buy a sand paper and shaved the pcb board by 1mm
[10:01:52 PM] well not exact 1mm, i think it was less than that
OWC Rebecca: [10:01:58 PM] That has voided the warranty.
Adi Chandra Hid..: [10:02:03 PM] maybe about 0.3mm
[10:02:24 PM] yes that voided the warranty, but it fit now and works just fine
[10:02:30 PM] i had to take a risk u know.
[10:02:49 PM] because shipping it back and paying another government tax is very expensive
OWC Rebecca: [10:03:05 PM] But you never consulted with techs to make sure you were installing correctly?
Adi Chandra Hid..: [10:03:30 PM] what i really want to complaint is, pleasee owc, if u want to send an item to a very distant place like indonesia (south east asia)
[10:03:44 PM] please make sure the item is tested, well fitted
OWC Rebecca: [10:04:06 PM] We do test them. I am sorry but this is the first time I have heard of one not fitting
Adi Chandra Hid..: [10:04:28 PM] well the item works well, but it was just didn't fit because of the pcb cutting is not as precise
[10:05:06 PM] im glad the item works really well, and the speed is much higher than the toshiba flash storage in my 2012 air
[10:05:48 PM] please make sure to double check your item before shipping it to a very far place. i know you were testing it, but i didn't think you were testing it by putting it in the macbook air
[10:06:10 PM] you must be using a converter like envoy to test it because opening air, fitting it, testing it will take much time
OWC Rebecca: [10:06:12 PM] That is how we test it. There is no other way
[10:06:36 PM] We test our SSDs in mac models.
Adi Chandra Hid..: [10:06:46 PM] u tested it by putting it into the macbook air unit?
OWC Rebecca: [10:07:20 PM] Yes. That is the only way we can test. We don't even make an enclosure for that model drive yet.
[10:07:33 PM] Even on the older auras we still test in an air.
Adi Chandra Hid..: [10:07:53 PM] well then, it might be your air unit is getting loose, or my aura pro grows a little bit when flying from USA to asia
[10:08:30 PM] ok then, I'm just glad the unit works really well after i shaved off a bit of the pcb board.
[10:08:38 PM] that's all i have to complaint
[10:08:58 PM] do you want me to give u a thread discussing about the aura doesn't fit?
[10:09:04 PM] that one came from malaysia
OWC Rebecca: [10:09:17 PM] I will forward this on but this is the first time I heard of the 2012 not fitting.
Adi Chandra Hid..: [10:10:13 PM]

[10:10:22 PM] that one was the 2011 version i think.
OWC Rebecca: [10:10:49 PM] That thread is dated 2010?
[10:11:03 PM] Sorry 2011
[10:11:16 PM] That is a 2011 model then not a 2012
Adi Chandra Hid..: [10:11:28 PM] yes that one was 2011 model, and mine was 2012
[10:11:42 PM] so u ever heard about the 2011 model that doesn't fit?
[10:11:55 PM] so mine is the first 2012 model that doesn't fit?
[10:12:38 PM] i love OWC u know, i really do because their products are great, and u can't find any third party that sell an alternative flash storage besides apple
[10:13:25 PM] but please, forward this issue, because i almost wasted another hundred bucks just to get the thing working
OWC Rebecca: [10:13:26 PM] That I have heard. We did have a few customers complain that the 2011 did not fit but some were installing wrong and others came back and fit our airs fine. I am not sure what happened with those. Overall we rarely have this complaint for the air drives as a whole.
Adi Chandra Hid..: [10:14:44 PM] i didn't do it wrong, i have pushed the aura to the max, and it's still didn't fit. the pcb board is not cut really well in the factory. by 0.2-0.3mm
OWC Rebecca: [10:15:18 PM] Had there been a batch that was cut wrong I would have heard about it and we would have notified customers to send them back.
[10:15:22 PM] This never happened.
Adi Chandra Hid..: [10:16:04 PM] last year i bought the memory and mercury 6G for my macbook pro, those items are working great until now. and recently the aura which had the issue, this scares me to buy another product from OWC again
[10:16:23 PM] ok that never happened, but it happened with my aura
[10:17:25 PM] i just need u to inform your boss, there is a single 2012 aura that the pcb board is not cut well, it didn't fit in some guy's 2012 air in indonesia
[10:17:28 PM] that's all
OWC Rebecca: [10:17:34 PM] I have.
Adi Chandra Hid..: [10:18:05 PM] i'm not asking for a new item, no im not, and i couldn't care less about the voided warranty because i believe the owc product is good
[10:18:18 PM] ok thanks rebecca, have a great day

OWC Rebecca: [10:19:00 PM] Thank you for using OWC livechat. You too!
