    A great little chainsaw and sharp as a razor! Supplied ready to use. Excellent value for a quality item.

  2. mattpalmer5 (verified owner)

    Super chainsaw, delivered to the door. Came with chain oil loaded and a full tank of petrol – excellent customer service. Very impressed.

  3. johnctaylor71 (verified owner)

    The second purchase from Radmore who are an excellent company to deal with, reliable and professional. The chainsaw was a replacement for a stolen item and I know the product is excellent.

  4. Stephen Gray (verified owner)

    Only recently bought so only used few times but really good wee saw. Chain razor sharp. Stihl are always usually quality products though.

  5. Stephen Gray (verified owner)

    Great little chainsaw so far but only used a few times. Usually quality products though Stihl.
    Upon reading other reviews people are saying they received chainsaw with full tank of gas and oil.
    Mines never came with anything bare bones in a cardboard box.

  6. neil chilvers (verified owner)

    Radmore & Tucker great service. Slightly disappointed with the Stihl chainsaw, does not start as easily as expected from cold and after filling with fuel .

  7. Lara Protheroe (verified owner)

    Great little saw and good value. It is speeding through our log piles.

  8. Stuart James (verified owner)

    I purchased this saw, having used a friends. Great weight and great power for the size, looking forward to using it more. Fast standard delivery and well packaged. Thank you!
