Swap your keys with a TI-30XS, and save your sanity
Reviewed in the United States on September 12, 2019
As many other reviewers have said, the silver reflective keys are the one big negative with this otherwise awesome calculator. Idea #1 - I did what others suggested and used a fine point sharpie to color in the button etchings. Slightly better, but the reflective paint still made the buttons hard to see.
Idea #2 - Turns out the Texas Instruments TI-30XS [https://www.amazon.com/gp/product/B000PDFQ6K] has the exact same keys as the TI-36 Pro. I swapped my TI-36X keys for the TI-30 keys, and my photo shows the before & after result -- completely legible keys! It's been so much nicer with this mod. Swapped the Arrow keys, 2nd, Vars keys too, since it looked better.
Yes, this means I had to purchase 2 calculators (hey I waited until they were on sale, don't judge me). And I had to completely disassemble both calculators. And I had to dremel the circuit boards out to get at the keys. But it worked! The result was totally worth it. NO REGERTS
(wait could this mean TI is trying to get us to purchase twice as many calculators?? Well played, TI.)
