The thread on bad sellers can be useful, but how about some recommendations as a counterpoint. So far my experience has been generally good with sellers there and it seems helpful to mention those who delivered products that worked well and matched the description.

Here are some of mine.

IC Components Store
Purchased:
Miniature mercury switches which were shipped quickly. The product matched the description and arrived in reasonable condition (some bent leads, not damage).
Dome switches with flex PCB leads, same as above.

zofipo Official Store
Purchased:
5mm APA106 addressable RGB LEDs which were shipped quickly and arrived with no damaged, packed well. The product was as described and spot checks among the 100 pieces have revealed no defective ones.

LOLIN Official Store
This is actually the official store of LOLIN (WEMOS) selling the various LOLIN/WEMOS ESP32 development boards.
Purchased:
D1 Mini dev boards and accessory boards shipped quickly arrived well packaged and all operational.

I will add some more as time allows, but this is a start, how about you? i

Thanks a lot for sharing the list with us. People often have bad experiences when purchasing from alliexpress. This write-up will surely help us to choose the right supplier.

I've never had a bad experience with an aliexpress store. More than 200 orders placed. A few that were surprisingly slow but I always got my orders. I've only placed one order for over $1000 and it was a bit entertaining to see if my bet would pay off or not. It paid off. Item one-tenth the price of a comparable item in the US (who likely just imported the same thing from China).

BTW: I think it would be especially helpful to know the sellers that have supplied good ICs and transistors since those seem to be particularly prone to problems. I have not used AliExpress for that, but at least one seller that is available there, Chanzon, I have purchased from on Amazon with excellent results.

I've never had a bad anything from Ali Express. I think most claims of fake goods from Ali Express are just as likely to be a user error or a lot that was somehow mis-handled during its lifetime (but unlikely). I don't know of any IC foundries thst will let a truck full of bad wafers drive down the road, or even bother putting the so-called off spec wafers into packages, put those off spec packages onto reels and let them get into circulation.

A potential problem with giving good reviews is that the sellers might get to the point where they consider maximizing profit to be more important than selling good product. So, it will be important for anyone having a bad experience using a recommended seller to post an update on this thread.

@Willen and I have both purchased 2SK596B N channel JFETs from shenzhenYida Store that tested good for Idss. I did 100% testing for Idss, and sampled cutoff voltage spec.

I purchased the maximum number that didn't cause an increase in the base shipping charge (40 pieces at $0.02 each). Shipping cost has gone up about 40% since I bought 2 months ago.

Yes, past performance does not guarantee future excellence, but it is better than shopping blind to know they shipped good parts.

Even what have been good vendors will let junk slip in. I do a lot of browsing on Amazon. When I find something I'm interested in, I shop around. In particular if I know it is a chinese product I go check AliX. Most of my problems have been with chips and capacitors. Not with transistors, regulators or hardware. Some of my regular and somewhat reliable vendors there are:
UltimateElectronics Store - electrolytic capacitors
Lushigher IC Store - Chips and transistors
jhiwor Store - Glass fuses and headers, etc.
Standby for Module Store - Just that, Arduino/Pi/etc. Modules, all kinds...
AiyimaTechnology Store - Bigger modules like power supplies and amps.
FSXSEMI FengShengXIn Store - Bought lots of chips and transistors there
Tnkmo Store - SMD chips and etc.
InShop Chip Store - Chips and Transistors
CZB6721960 Store - Power and Relay boards, heatsinks, etc.
Mobin Store - This is a fun spot to browse, lots of tube radio kits and such
FXI Electronics Co., Ltd. - Chips and transistors.
I always test chips on arrival with a basic test circuit for go/nogo. It's time consuming but I'm retired and they all sell bad chips from time to time. I've had multiple lots of bad LM318N fast op amps over the last several months. Some won't do anything or have a slew rate of ~10V/us when the spec is ~115V/us. Out of 6 lots, one lot of 10 was in the low 80s to high 90s V/us. Also check capacitors, especially ceramic. I expect +/-20% and often they are more than 100%. So Caveat Emptor! And always file a dispute if you get junk sent to you! It seems I have to ~10% of the time but have never had one not found in my favor!
