Mmmmm, Barska.... I bought a cheap pair 15x70mm Barska binos about 12 years back, on sale for $70ish IIRC. Figured they'd be good enough for a leave in the truck set, inexpensive & not gut wrenching if they got stolen etc. After a few months in the truck during warm weather , they got a little gooey. After an entire winter, I went to use them & the glue holding EVERYTHING together had dried up. Focus wouldn't budge, pieces started coming off in my hands while trying to coax adjustments lol.
