Where to get legit nRF24L01+ modules?

There's no reason to continue using nRF24L01's anyway, except for legacy situations. Their only virtue is cheapness, and the nRF51's offer a good substitute for that.

Some news. After playing with NRF5 and the NRF24 protocol.
The red EBYTE modules are fakes.Over the N of NRF is a dot. I have ordered these modules: https://aliexpress.com/item/Wireless-Module-NRF24L01-original-2-4-Ghz-RF-transceiver-SPI/32712174920.html they have an rectangle over the N and responding line an original NRF24L01. Maybe this helps to identify originals.
The difference between both modules is in NoACK attribute handling. Fakes always responding with ACK and sending inverse NoACK attributes. So fakes have problems communicate with original modules.EDIT: This was an issue at the NRF5 side.

Here we go again... Nordic is a fabless company. Therefore the laser marking on their genuine models can be different with each batch. There is no known way to tell if a module is genuine or not from the outside of the module.

First I've heard of this. How often is "from time to time"?

<0,1% of packages. I have three versions of the ESB protocol code. With the published version, the module hangs when PAN#102 is triggered. My second version was a try to fix this issue by adding some timer code. With this fix, the NRF5 looses more packages than before. The version I currently working on looks more stable, is easier to debug, supports the fast ramp up mode partially, but it's not complete yet.

Sorry for my NRF24 clone post yesterday. The ACK bit was an issue with the NRF5 platform. I had switched the memory region to handle TX/RX/ACK packages separately. Sometimes the received packages are written in the wrong region. I had seen my testing ACK bit. Now, I have changed my NRF5 code and I can't see no difference between the modules, I have. ACK and timing are exactly at the same level.
