Maybe off-topic, but you as the thread opener asked, hence I dare to answer:
I like it very much - otherwise I wouldn't have bought it.
Why a Trinovid 10x25? In the name of "simplify your life" I have boiled down my optical equipment to 1 bridge camera, 1 scope and 2 binos. Period! I don't want to possess commodities anymore that I don't use sufficiently and I want to stay away from the all too common buy-and-sell cycle. The Trinovid 8x42 BA is non-negotiable but sometimes too bulky therefore I need an additional compact "EDC" bino. Moreover, at times I'd like to have more magnification than 8x, besides 10x25s usually have longer barrels than 8x20s that fit my large hands better. Therefore a 10x25 delivers the higher value added to me.
In the past I already owned a Trinovid 10x25 BC, then a Nikon 10x25 HGL and later an Ultravid 10x25 BR. (I also tried a discontinued Zeiss 10x25 but it did not fit my eyes.) I had no problem holding them steady, got used to the small exit pupil and the modest field of view. The Leica push-pull eyecups are a perfect match to my eyes as well as to my glasses - full field of view, no blackouts. Although the Ultravids are waterproof and might provide a smidge more contrast than the Trinovids I prefer the latter: the dioptric correction - very important to me - does not restrict the range of the main diopter (like in the Ultravid), the price is decidedly lower und last not least I like the appearance and feel of its classic design that has for good reason remained essentially unchanged since 1975.
