What is the opinion of Reddit about the
X-keys Keycap Cherry MX Compatible (Single, Transparent, 10 pack)?

Nice I will look on amazon. Thanks

Edit: is it these https://www.amazon.com/X-keys-Single-Transparent-Keycaps-pk-10/dp/B00FYO8EDC/ref=pd_sbs_147_14?_encoding=UTF8&pd_rd_i=B00FYO8EDC&pd_rd_r=NS71SNTA9016BESNMNBS&pd_rd_w=IN0aS&pd_rd_wg=I6WQv&psc=1&refRID=NS71SNTA9016BESNMNBS ?

Nice build. For something like that I would be tempted to use clear caps like these but I don’t know where to get any that are not 1u caps.

They are clear relegendable caps I was able to find on Amazon in packs of 10

Looks like this is the company that makes it… Maybe they can give you information on replacement buttons?

Alternatively, there are colored relegendable keycaps on Amazon for $6 per pack that look similar, but work with standard cherry mx switches…
