    Very immediate delivery by R & T – same day!! (I’m pretty local to Exeter, though). So far the saw has been faultless – starts easily and is a beast to cut with. About the best price I could find on the internet. Very happy with it all.

  3. Dave (verified owner)

    Delivery was slow but that’s ok as COVID-19 caused problems,
    The saw is excellent as expected the internet Radmoretucker price was the best I could find,
    Good deal and good service wouldn’t hesitate to buy again
