We commend your staff, Josh, James & Aden – excellent representatives for your company, together with efficient and prompt installation of the new unit.
Suffice to say you are very fortunate that we have returned your “boys” – we would be more than happy to keep them……😀. A pleasure to have them here.
We will see if we need another unit, after we try out the new one.
Every thanks and good wish,

Kind regards,
