Bought these to replace the analog modules in two of my friend's ps5 controllers. They are the same color and the same resistance I guess? not sure what the 2.3K really means. I am guessing these are exact replacements since the company name on the originals in the ps5 controller matched the replacements. It was packaged well nothing was bent or in a compromising position. Overall, no issues so far in the short term have been using these controllers for the past 2 days and also tested them through windows USB controller setup and found no drifting or issues. The set came with 4 but I only needed to use 3 out of the 4. If anything changes in the long term, I will update my score/findings but so far, no issues with it.
