I have one of those too and have bought several for friends and relatives.
I have several other Chinese-made scales. One is a kitchen scale that weighs up to 10kg with a resolution of 1 gm and a jeweler's scale that goes up to 200 gm with a resolution of 0.01gm. I also have three different luggage scales with a maximum load of 50kg. I've been using all of them regularly for many years now.
I have a digital bathroom scale from years ago. I guess the electronics is a lot cheaper now. This one has a single strain gauge and uses mechanical levers to put the weight of each corner of the scale onto the strain gauge . If I lean too far back (meaning not leaning forward at all) it won't rea d at all. I have to lean forward a bit and the weight can vary a bit. May be it's time for a new one.

Received at 2pm my time, looks AOK.
Do let us know how the parts turn out.
Yes, *test* them properly (as I'm sure you of all people will!) and please let us know the outcome.

These Avia HX711 ICs are an example of parts that'll never be counterfeited, they're too damn cheap. Tens to hundreds of millions made and sold for pennies, to be used in scales of all types. They work extremely well. It's most likely they'll never be second-sourced either, they're quite sophisticated and hard to make.
Hah, one set of AliExpress parts came roaring in one day later, using another shipping firm. Meanwhile FedEx didn't pickup my package to CO.
The above parts were rapidly sent from Hong Kong by a Chinese shipper, SF Express. Recommended.
My second set of 100 from an AliExpress seller came in just now, by DHL, who shipped it here in two days. But the seller took six days to get it to DHL in Hong Kong, bummer!
Actually 1st set I ordered, 3rd set received. But all three shipments came in soon enough for our little emergency. Conclusion, AliExpress is OK.
