Ill report back if they die before then - we often find that cheaper earbuds dont last very long. My daughter is currently wearing a size 9 in toddler shoes. My only issue with these is that there is a little bit of latency in the sound when watching video (say Netflix, youtube etc). The hand-strap came off about 6 days after I bought it and then the little ball accessory came off about 2 months after purchase. Make sure you purchase the mounts, as this item just includes the track. Pros:-comfortable out-of-the-box, requiring no break-in time-closed-toe for added protection-breathable in very hot weather-although not categorized as a waterproof shoe, I wore these in London rainstorms and my feet stayed dry-wedge heel adds style and goes well with dresses, as well as pants, jeans, shorts, etc. I dont know what Subaru OEM cross bars look like but imagine these are the ones they use. Very strange for a US-based company. Again, my 5 stars are not for its stylish look. And the material of the sandal is not like real Havaianas, it is way softer and not as stable and thus not offering as much comfort as real Havaianas (my feet get tired super easily and start hurting).
