Hi! Im fairly new here i only posted one before. But im reviewing the sci fi lasers sf501b 445nm laser that ive had for maybe a month now. Ill divide it into seperate sections.
Ordering/Customer service:
I ordered the laser on july 28. I did have to wait about a month for it to ship and i was trying my best to wait patiently! Some of that time was due to problems with fedex. He then shipped it via ems and I had the laser within a week, most of that time it was sitting in customs. During the time i was waiting, I had some questions which were answered promptly and received emails a couple times telling me its status.
Build quality:
Everything is put together very well. Everything is fit snugly together and there are no rattles. The on switch has a firm satisfying click when pressed. The one imperfection is the front of the laser is off-center from the plastic case. I cant seem to figure out how to post pictures of it from my phone. If i figure out how to do that i will post it.
Performance:
I am very impressed with the performance of this laser. I ordered the 1.3-1.8 watt version and he emailed me with the lpm check and it was 1.901. This laser burns basically anything it touches. The beam seems to go on forever when shined in the sky. I am able to see it on a hillside at least 200 or 300 yards away in daylight and anywhere i point it at night. I calculated the divergance as 0.003124. Not sure if thats calculated correctly or not though i just tried to follow directions online to do that.
Im conclusion i am very satisfied with this laser and i would definately order from them again! And if i figure out how to post pictures i will add them. Any help on that issue would be welcome!
