Sounds wonderful
So is there something with resistors (could be other components) where if they don't fail in the first week they'll probably last forever or there is always a risk?
Resistors, even Chinese cheapies, are not something that fails often, unless you abuse them with excessive current, voltage or mechanically. If the pack from Banggood is cheap, just go for it, it is probably only a few bucks that you would lose in the worst case. I wouldn't buy precision resistors from such place, but for general tinkering they are most likely more than good enough. I am often buying similar resistor/capacitor kits to stock up my component drawers and never had significant issues. You can get rusty parts even from Farnell, so ...
For experimenting with some basic circuits you really don't need to care about whether the resistor is metal film or carbon, it is more important to actually
have that resistor in the first place.
When buying components on AliExpress/eBay/Banggood, etc. always check the reviews/feedback of the seller, ideally on the same item. If there is a problem with it, someone will have likely pointed it out already. You could always get a DOA item, though. Shit happens, but most sellers even from China will try to help you out, because they care about their ratings (bad rating = no sales, the competition is really cutthroat and margins slim there). Just be reasonable and don't demand a free replacement for a $2 item no matter what. If the seller offers that, fine, otherwise the logistics around will cost the seller more than the item. In the few cases I had to deal with this, I have got a discount on next order or the replacement has arrived with the next order. Both fine with me. Returning money is rare, because it is expensive for them and a hassle unless you have paid with something like Alipay, especially for a small order.
I am also vary of items with 0 feedback - there you are on your own. Most likely the item will be OK, but it could also be a major lemon. Buy only if you will not mind throwing the item in the bin should it not be as you have imagined.
Now what I am rarely buying at these places are semiconductors - the chance of getting fake parts, especially for popular and easy to fake components (= relabel similar but much cheaper part, so it sorta works ...) is fairly high. Things like power MOSFETS and ICs I will rather order from an official distributor. On the other hand, if you only need a few jellybean transistors and LEDs for breadboarding, that's mostly no problem, even if you get relabeled/fake parts. They will rarely sell you a transistor or LED that don't work at all and for a breadboard it doesn't really matter if the LED dies 50% earlier than a real KingBright or Cree one. Power LEDs can be iffy, though, often with dead chips.
The other thing I don't recommend buying from China are electrolytic capacitors, especially if it is for repairing a switching power supply. You will almost universally get junk.
Basically, if you are buying parts for just trying things out and learning, don't worry too much about it. If it is for something critical - like a school project, power supply that could fry something expensive if it fails, something for your job, demo for the investors of your startup - there saving a few pennies by not buying from a big name distributor could cost you a lot more if you get unlucky. As always - it is a trade-off.
