    I am very pleased with the new key board. Which was fitted in same place as my old one was. That was on my kitchen tiles. No mess. 2023 And I like having the box outside lit up at night. Family business. I’ve met Luke and his son . And his son . Very polite.. I’ve just had my year service. Would recommend them..
