Do backpacking pillows leak or fail over time?

Durability is the most consistent complaint across the category. r/Ultralight and r/backpacking threads include first-hand reports of valve leaks on both Trekology and Sea to Summit Aeros pillows, sometimes within the first 10 nights of use. Hybrid foam pillows and pure stuff-sack designs have fewer single-point-of-failure complaints but pack down larger.
