As promised here's the full story of my underspec Spartan 589nm. I didn't post this before because I had hopes of convincing Adam to replace it or issue me a partial refund. I did, however, warn Jmillerdoc because he was planning a second GB at the time. He eventually gave up on the GB due to this and personal reasons.
This is going to be a very long post, so here's the TL;DR:
I was sold an underspec and mode-hopping laser and Adam refused to replace it under the argument that *all* of his 589nm lasers are underspec and unstable.
Note: I replaced my real name and location on the quotes below, everything else was copy-pasted from e-mails exchanged with Adam. I also underlined the most important parts.
After brucemir posted his review of this laser I decided to order one. That was before the first GB, so I had to order individually. Before ordering I contacted Adam to make sure the laser would be on spec. Here's what I asked him and his answer (we had already exchanged a few e-mails about shipping):
I placed the order on May 13 but only received my laser on August 3, after the first GB participants had received theirs - that's mostly not Adam's fault, international shipments take a long time to arrive here. His only fault was that he could have told me the laser was out of stock *before* making the sale, but he did it afterwards:
Unfortunately I was in for a huge disappointment. My laser was underspec and mode hopping wildly. Here's the message I sent to Adam:
And, to my surprise, here's what he answered - without even asking for a video or LPM pictures:
Initially I had thought the poor performance might be attributable to temperature, but the weather got colder a few days later (about 17-18°C) and the laser was still mode-hopping and outputting around the same power.
I got very pissed after his reply. He was either lying before (he promised that the laser would be TEM00 and on-spec) or he was lying afterwards (when he told me that all his lasers are underspec). And if he tested the laser and knew it was underspec why did he ship it? Not a good way to do business.
Anyways after a few more e-mails he declined to replace the laser or give me a partial refund (which would avoid the risk of having to ship the laser back to China). He told me I could either keep it or send it back to China for a full refund.
I wanted to warn you guys that any future lasers from him are probably going to be crappy, but I didn't want to post this in the open because if I decided to return the laser he'd most likely take revenge and not give me my money back. I did tell Jmillerdoc in PVT because he was thinking about doing a second GB.
At first I didn't know what to do. Adam is obviously not trustworthy. He has ripped RHD with a "full refund" scam in the past on a very similar issue: http://laserpointerforums.com/f41/d...ery-displeased-so-far-lpm-7mw-24mw-64890.html
Jmillerdoc tried to talk to Adam and see if he could replace the laser but Adam didn't change his mind. He didn't tell Jmillerdoc that all his lasers are underspec, but he refused to guarantee >50mW power output for a second GB. BTW: Jmillerdoc, thanks for taking your time!
In the end I decided to keep the laser. Couldn't take the chance of sending the laser back to China and not receiving a full refund. TBH even if I was 100% sure he'd issue the refund I still don't want to have that WL gap on my collection forever in case the recent news that CNI is stopping production of handhelds as of 2015 turns out to be real.
Buyer beware: if you buy one of these there's a reasonable chance you'll end up with an underspec and mode-hopping laser.
Edit: Update - DL sent me an automated e-mail a few days ago with a link for me to write a review of the laser on their site. I wrote the review, gave it 1 star (no zero available).
It's been a couple days and the review hasn't showed up there. They're filtering the negative reviews. So now we know why they only have 3-star reviews on their page.
Not even DX does this. For crying out loud.

Atomicrox said:Hi Adam,
I don't mind waiting for regular mail (most stuff takes 1-2 months to get here from China anyways), as long as it's well packed and arrives here undamaged.
Before I place my order I just want to make sure of a couple things:
-You do guarantee that it does 50mW during 1min, right?
-Does it have the FDA 5 second turn on delay? I pefer if it doesn't.
-Is the beam profile TEM00?
Best regards,
Atomicrox
Adam said:Hi Atomicrox,
There is no problem of shipping your order by post mail.
The average power is over 50mW for 1 minutes continuous operation
there is not 5 seconds turn on delay
the beam profile is TEM00 when the operating temperature is normal.

Adam said:Hi Atomicrox,
Thank you for your order. Your order will be shipped by next weekend.
I am sorry the product is temporary out of stock. You will receive another email with shipping info.

Atomicrox said:Hi Adam,
This sunday I received the laser but unfortunately it's metering below the specification.
The test was performed with a fully charged (4.17V) unprotected Panasonic 18650, ambient temperature was 22.5ºC (slightly cold by local standards).
On a 1 minute run it had a minimum of 29.9mW and a peak of 58.4mW, but most of the time it floated around 37mW. It stayed above 50mW during maybe 10s of the whole run.
It's also mode hopping like crazy, though it's only noticeable with an external lens to amplify the dot.
Since almost every member of LPF that got one received an overspec unit I think there's something wrong with mine. I haven't posted my review there yet, thought I should contact you first.
Best regards,
Atomicrox
And, to my surprise, here's what he answered - without even asking for a video or LPM pictures:
Dear Atomicrox,
I respect your testing result. I believe that it is correct.
These Spartan yellow lasers are just performing like this. It can hardly stable above 50mW especially when it is warm.
Actually every lasers was tested properly before shipping.
Each laser is different with the others. For example if a laser keep at over 50mW for 20-30 seconds then probably it dims to be around 5mW.
Your laser average at 37mW and peaking over 50mW. that is already very good compare to other yellow lasers.
The substance of making the yellow lasers are just very unstable. Mode hopping is common.
For example our 55mW viper laser can keep over 65mW for whole one minute run.
However all of our 50mW Spartan yellow laser are not over 50mW for whole one minute.
You are correct the performance is below the specifics on the site page. And I can tell you yours is not the only one. I think all of our 50mW yellow laser pointers are not over 50mW for whole one minute.
I wish you can keep your good laser and handle it with care all the time.
However if you want to send it back for a refund then please let me know and I will send you return instrucitons.
Replacement is not possible because I can hardly find another which is obviously better than yours.
Sincerely Yours.
