So I recently purchased a 473nm from jetlasers and I just received it today.
Buying:
Price: $324
The actual buying process was pretty simple as they support PayPal which was really convenient. It went as smooth as possible not a single complaint.
My one and only issue with the purchasing was the fact that emails leading up to the purchase led no indication of the 50mw version coming back. I would have definitely waited and spent the additional $30. It is not really anyone's fault I would of just assumed they would have wanted to promote new upcoming products? So now two weeks later I just receive my 30mw and now suddenly there is the 50mw for sale.
Shipping:
The shipping is another story. I placed the order on 3/29 with all intentions of it swiftly shipping within a 3 day or so window. However, there was an obvious lack of communication as I was never notified there would be a delay due to Chinese "easter" holiday as I was told later on. So my order did not end up shipping until 4/6. A bit of a let down with the whole lack of communication thing, but they were prompt to reply to my emails so overall customer service wise it went well.
Another discrepancy with the shipping was when I did finally get a tracking number I was told it was for FedEx. So I tried FedEx to no avail. So before I emailed them back again I decided to just give it a try on DHL and it ended up working. So there was also mis-communication on the shipping service and tracking as well.
I received it today at 3pm 4/10 from DHL which was 3 days earlier than original predicted by DHL. So the shipping speed was excellent.
Packaging/contents:
Again I will let photos speak.
The packaging was very nice. The content however I was kind of disappointed but surprised at the same time. Right off the bat from seeing previous reviews I noticed only 1 style battery tube which was a little disappointing, but I can lives with it. Surprisingly I noticed the key switch tail cap which I know is a newer update so that was nice and best of all IT FUNCTIONS. The battery charger is nice, but not a necessity. It also came with the battery tube for 18650 and 2 microfiber clothes id assume for cleaning the lens.
Also it did not come with a power graph just a warranty card.
Laser:
Now for the laser itself. I've read about them, but now actually having one I definitely agree. The pro host is a BEAST it's huge and feels like a brick in your hand (in a good way). It easily feels like the most solid laser I own. I also noticed on the one I got the momentary switch has been switched to a metal button instead of the rubber one that some previous reviewers kind of had a gripe about with it "sticking" so it seems like a solid upgrade. The dust cover screw in is very nice as well. Some people have said you have to be careful with crown as to not cut your fingers, but I don't seem to have the same issue personally.
Now I do have one gripe with the laser/one of the contents and that is the battery tube insert for 18650s. It just doesn't have a snug fit as I had expected. If you use it with a 18650 and move the laser around you can hear the battery shift inside. It still functions properly and does the job, just to me personally it is kind of lackluster. 26650 fits nice and snug though and I can see why they obviously recommend them to be used.
The 3 small lights by the power button light up red when the laser is active (using the key to activate the laser) and they go off when de-activated.
I will only provide one picture as you can go to their website and see plenty of photos.
Beam Divergence:
I brought my digital micrometer home from work today and decided to give my hand at measuring beam divergence using the beam divergence calculator. I measured at the aperture (or as close as I could with the large crown on the host) and again at about 5 Ft (using a tape measure for distance)
After measuring both in mm and plugging them into the calculator along with distances I got a result of approximately 1.17mrad.
JetLaser's website has a list of 1mrad divergence adjustable with focus. So assuming mine is not perfectly focused at the moment the result is pretty nice.
Dot:
I did the best to take a picture of the dot by itself. It seems to hold TEM00 pretty well after it's approx. 20sec warm up. During warm up there can be some jumping to what looks like possibly TEM01.
Power:
Measured the power with a fresh Efest purple 26650. For 2 mins.
Overall a little disappointing it doesn't seem to be as over-powered as some of the other jetlaser products I've seen reviewed, but it is over-powered a little and surprisingly very stable and it does meet the specifications it was sold as so I can't complain either. I will be interested to see what their graph shows and to try power tests at other temperatures.
Test 2:
So I got my new battery in today I bought just for this laser. The battery used in the first test was an efest 26650 3.7v 3500mah with a rated discharge current of 32A continuous/64A pulse (I use 2 in my 462nm laser). For this laser I decided to purchase a different efest battery which is the efest 26650 3.7v 4200mah with a rated discharge of 20A continuous and 50A pulsed. In this test I also let the laser warm up for a 2 min run, cool for a minute or so, and just hold it for about 30minutes or so to help warm it up and then test. I got completely different results with another 2min run.

Beamshots:
More later when it gets darker.
Conclusion:
Overall I would have to say there were both high points and low points in the purchasing and receiving of this laser. However, I must say this seems like a hell of a laser for the price and wouldn't hesitate to deal with jetlasers again.
Thank you for reading
