I've found the LPMR to give a much better "true to life" recorded image than other daylight cameras that are simply attached one way or another to the end of an NVD and was optimized to record an NV image.

That being said, I will say that lately in my experience, WP Photonis ECHOs take the best "through the tube" photographs I've ever seen, up to an including L3 UF "high spec supertubes," which look gorgeous "in real life," but in photographs, the quality of the tube, simply does not translate as well. Conversely, I've seen some beautiful looking images taken with WP ECHOs, especially when you're talking about iPhone photographs.

I'm sure there is a camera-tech explanation for this somewhere out there, but cameras aren't really my forte, all I can really judge is what I see versus what I record and my own subjective impression of how they stack up.

Meanwhile, re: the LPMR's attachment method to the PVS-14 accessory adapter ring in particular--

The ring "clamp" is actually designed so that it can be tightened by squeezing or even heating the "arms" of the clamp, and the material is designed to take a "set," though in the months I've been using it, I've certainly found that it benefits from periodic re-tightening. For me, the biggest issue with the rotation is not that it rotates on the ring, but actually, that it can sometimes cause the ring to begin unthreading if it rotates for some reason, to whit, I might recommend that some folks who are finding they have issues with rotation, not only check the fit of the LPMR to the accessory ring also check how well the accessory ring is threaded into the eyepiece lens, I've seen some that are barely finger tight (I will often remove them from goggles if not using any accessories), while I've seen others that seem like they were installed by a gorilla with hydraulic arms.

Part of the reason for the somewhat "wide" tolerances on the LPMR clamp is the wide range of accessory adapter rings available out there--not everyone may realize, but there are several different variants out there made by several different OEMs, all of which have slight differences, including some made of aluminum, some from Delrin, some from other, cheaper polymers. Consequently, it is possible for the LPMR to "show up" loose on a particular accessory adapter, new out of the box. That being said, they can be tightened to fit most, if not all lock rings out there with a decent amount of tension.

Now, this is not to dismiss customer complaints about the LPMR, needless to say, we've forwarded every complaint to BCO and we've discussed with them various minor improvements that could be made to the devices (some of which have been instituted already).
