They are pretty amazing, even if they were $1k more.
I have been putting them through their paces lately. I don't like to sell stuff that I haven't personally got to use fairly extensively and decided that I like it. For shear image quality comparison, I set up a little blind test. I had a few friends come over that don't own thermal and don't really know anything about them, so they don't have brand bias....because they have never really heard of any of them. I also brought the wife out and had all of them look through the Pulsar HD19A, FLIR PS-32, and an EOTech X320. All of them picked the Pulsar HD19A for image quality.
Next I gave them a rundown on controls. The pulsar controls are what I have tried to get other companies to do; set them up like a military device. Simple, and not too many functions per button/wheel. I really like that you have a dial for brightness and contrast on the pulsar, a button to NUC, a button for power, and a button for zoom, all laid out nicely for actual use in the dark. So, out of the 3, the Pulsar came away as a very clear winner by a large margin....and keep in mind, I sell all 3 units. What is even more impressive is that it does so for $1000 cheaper than the FLIR, and $1500 cheaper than the X320! You can bump up to the 38mm lens and get a really awesome image and better performance in foul weather, and still be cheaper than either.
As has been mentioned before, the housing on the Pulsar does not seem as robust as some other units. However, my dominant arm has poor dexterity due to taking a large chunk of metal in a nerve bundle. So, I accidentally test the durability of about everything I grab at some point. I've managed to drop the 19A on concrete once and on tile once, without damaging it. However, that is nowhere near a comprehensive durability test, but at least it will handle some minor abuse. Some polymers are incredibly strong. While I don't know what they use, I would imagine it will have a long life if taken care of and subjected to minor drops and bumps, etc. of normal hunting use.
As small of a thing as it is, my absolute favorite physical quality of the monoculars is the lens cap. How innovative is that!? You simply rotate the lens cap 1/4 or a turn and the lens cap, which looks like a shutter, closes and opens.
My least favorite thing is the eye cup. It is very poorly designed.
