"I am a scholar and writer - using my Mac 14h/day. With Retina 12' (2016) my keyboard was twice changed and again I had trouble with 3 keys. I ordered it (I lived in Italy but work in Poland) and we were in a Covid 19 crisis. At my university in Warsaw something happened - they never got the packet. I wrote to Peplacement Lapton Keys and they send me the second packet FOR FREE. I appreciated a lot this - while despite being uni professor my salary is not very high and it was an emergency situation. So, I am very happy to be their client! Thank you Replacement Laptop Keys!"
