The LEDs themselves in most cases are really REALLY durable, it's the shitty electronics driving them that fail.
Fixed that for you:
I buy stuff from aliexpress now and then, but just things that I don't care much about or don't need to rely on. In many cases I prefer to buy locally from a guy I am aware buys his stuff from aliexpress too and adds a margin, but there's at least some chance he already has that product checked out, shipping is much much faster and I get customer support under local (EU) regulations, get warranty replacements fast or the right to return purchased goods in some cases... Just saying.
Fixed that for you:
Buy a set from China direct, wait 4-6 weeks, if they fail after 6 months, they have only cost you a dollar, oh well, no problem, swap out for your original bulb, buy another one, only wait another 4-6 weeks, swap to the new arrived ones, and violin! another 6 months of peace.
