Best and worst overall quality/value components/tools/gear from AliExpress?

I'm seriously addicted to picking up UNO lightweight stems. I've swapped over to -17 degree stems on both my road bikes!

It looks a bit odd, why not use a flatter steerer top frame to stem interface thing and a stem with a more logical angle? Or the same stem if you can handle the drop.

I might slam it some more, but I haven't decided. I notice the -17° put me in a more snug cockpit position which I like for the downhill and also lowering my body position, but without stretching me out as much (like going with a longer stem).

Steel pedal expanders. Mine are from Risk I've seen them branded differently
Strongly recommend if you don't like having clean threads or skin on your knuckles. I thought the threads would still be fine but no, it took me an hour to remove them despite all the grease I used. Metal is very soft and bends when uninstalling, threads are toast after 1000km.
Thankfully the threads on my PM crankset are still okay. My look pedals were ruined so I'm gonna try the ultralight zeray pedals as a replacement. Hope I don't give an update from the hospital

Had a similarly shitty experience with ZTTO pedal extenders

They snapped on an MTB ride...luckily riight at the end of a hectic descent. Never again

Yikes! Mental note, don’t use pedal extenders!

Good
ZTTO Dropper Lever/Remote - Pretty much as good as it gets, smooth operation.
ZRace Blade Crankset - Very high quality, the cnc machining is top notch, steel axle/shaft is heavier then aluminium versions but it wont break in comparison.
ZTTO M1 boost wheel hubs - High quality finish, light weight. The 56t ratchet seems to hold up to my probably less abusive biking compared to other people or I was lucky with getting two ratchets that align/engage perfectly (which is very important in DT style ratchets).
Cooma and Delt brake pads - Various types, works great. There's better pads out there of course but waaaaaay more expensive.

Bad
ZTTO Chainring protector/guide - I did not like it, super flimsy plastic mounting points for the protector. The chain guide is probably fine tho, haven't used it.
