My Pico 4 works well with BMS 4.37, however a word of warning on the Chinese-made interfaces that are sold on ebay.
They all look to be the same, but sold by many different Chinese-based sellers, as so many of their products are these days.
When mine arrived (to UK after 3 weeks) I was very happy and got to using it straights away. The fit is very snug I mean very snug! With prescription lenses fitted, my nose and eyebrows were touching the lens rims. But I was happy, as the FoV seemed better, which was one of the main things I wanted, along with increased comfort.
However, after a week or so, I started suffering from pretty bad eye strain, which got more and more intense in a very short space of time. In the end, I switched back to the OEM interface and guess what? Didn’t notice any difference in FoV and it didn’t seem anywhere near as uncomfy as I’d thought it was!
I’ve seen a lot of people wanting one, so thought a word of warning was in order, as these seem to be the only ones currently available.
