If you're going to get a Chinese made roof binocular, that doesn't carry a label from the major "manufacturers" then, you ought to pick one of quality vs a cheap "also ran".
This Spina surprised me.
I tested this unknown against my Fujinon FMTR-SX.
I enjoyed the views though this newcomer MORE!
The color is good, the focuser is well knurled and damped and the extendable eyecups have 4 positions. Nice!
It's nicely armored and has internally locking objective covers. And, it sure is lighter than that Fujinon.
