If I ever decide to buy another DPSS 532, it'll probably be from Jetlasers. I don't think BTB will respond back to me telling if my laser is fine or it was damaged in shipping. I tend to think that it wasn't damaged in shipping and it's just how the laser was sold.Every unit is different--luck of the draw and shock free shipping really--could be yours got rattled in shipping --it happens---people have been generally pretty happy with laserbtb 532nm lasers---some a little underspec but not a big drop like what you received
Here is a 7 minute test of a PL-E Pro 400mW 523nm : https://www.youtube.com/watch?v=AZbwSfBE4Fc
Google "you tube jetlasers" there are dozens of videos.
