My bud has two OASYS thermals, one is a UTMx a 17 micron handheld/clip on thermal one model iteration from the current model. The other is a UTC, which is also 25 microns and one or two model iterations from current (the current model is the UTCxii, which is 12 microns.)
The view through the UTM is very nice and "smooth," you could look through it for hours without eye fatigue. Compared to my IRD MKII the image was smoother, less contrasty, but performance was similar as far as I could tell - my 35mm MKII is 2.45x, the UTM is 1x. I would say the LWTS, UTM and IRD products all have similar views, with the LWTS and UTM having "smoother" views, the IRD's having slightly more "contrasty" views. All similar in performance though, so the IRD shines for price.
The UTC is a remarkable, specialized clip on. It is useless as a handheld since the screen is tiny. But even with the day scope at 10x (which didn't quite provide a view of the screen which filled the view through the day scope) the view was pretty crisp. Similar at 10x to the MKII or UTM at 2x digital as far a sharpness. Usable with the day scope at 20x. A true long range capable thermal option. We could ID deer vs. raccoon, fox or coyote at well over 1,000 yards. If the marksman was up to it, shooting at that range was well within the UTC's capabilities.
With plenty of deer, a couple of fox, coyotes and raccoons to spot and watch, it was fun comparing the thermals we had along. I had my Pulsar HD 19A and my IRD MKII, I wish I had brought my Pulsar HD50S. My bud had the two OASYS thermals. What was interesting was the detection range differences. The thermals with either day scope magnification or native magnification could detect more critters, even when the resolution was similar and, in the case of the MK II, when the lens was smaller. The 19A could detect deer standing in soybeans to about 900 yards, but struggled with deer standing at the edge of the woods at 600 or so, where the resolution and 1x wouldn't permit separation of the hot spot the deer represented from other not quite so hot spots, like tree trunks. The 640 units didn't have that issue.
Fwiw, there are a couple of UTM's and UTC's similar to the ones my bud had available for sale, with a traceable, legit provenance and bill of sale. IIRC the pricing, it was $7-8k for a UTM, with all of the kit they come with from BAE originally, including Wilcox weapon mount, cords for recorders, etc.
