A six year problem - over the past two years maintained by Dwyer but not sold by them - was really on its last legs. After an extensive, in-depth discussion with Jamil, we decided to buy a new Bosch unit from Dwyer and get a superior product with superior after-sales care.
Jamil worked wonders to have the unit installed the next day, and was very capably handled by Nabil and his assistant Charles. Well done!
