Grade B ryers sre sold with a 30 day warranty. This warranty covers manufacturing defects, but does not cover wear and tear items such as cables, switches, motor brushes, hoses, nozzles etc. Grade B machines have been lightly used for only a very short period of time. They will be in excellent condition with very minor marks or scratches. All refurbished dryers from Master Service have been serviced and repaired to factory standard by our fully trained engineers. All faulty parts will have been replaced and the machines are supplied in a plain box.
