5 stars, no brainer - I purchased my first machine QPO 25, three years ago, having spent time by phone talking through my needs. The advice was spot on, I have purchased items from PST over the years, the orders are always promptly handled, usually arriving the next day. I had cause to return the machine at one stage due to a broken switch, they could not have been more helpful, I had the machine back on site 4 days later. I am currently arranging to get them to service the QPO 25, & when the need arises I shall have my other sprayer serviced by them. More than happy. 62 year old - P & D for 36 years.
