  1. Nick Adams

    Very sturdy tool as I’d anticipated. Does the job very well – grass and weeds against hedges and fences. Battery life enough for my needs – and the bonus – it’s the same battery as the hedge trimmer!
    Communication with Radmore and Tucker was very good and delivery was excellent.
    Thank you

    The strimmer seems good value, looks professional and I really like the fact .that it runs on the same batteries as hedge cutter. I am pleased with the prompt delivery service.

  12. David Wigglesworth (verified owner)

    Great quality product as always from STIHL and very competitively priced, delivery was also quick.
    The strimmer was well packaged and easy to assemble out of the box, it looks and feels quality. When charged make sure the battery is pushed firmly into the body of the strimmer until two clicks are heard, initially I thought the unit was faulty as it didn’t work. In operation the strimmer has plenty of power to handle most garden tasks although I found the spacer bar more of a hindrance and felt that a strap would have been a useful addition.
    All in all a great piece of kit and recommended.

  13. E Lambrecq (verified owner)

    As I now struggle to start a petrol strimmer , this cordless one is ideal for me, and more powerful than I thought it would be, so well pleased.

  14. Gordon Brown

    Chose Stihl for their reputation. Chose this model so I could use the AK10 battery from my hedge trimmer. Battery lasts a surprisingly long time. Well built , easy to handle model. Reasonable price. Easy to change heads . Works very well.Excellent service from Radmore and Tucker.

  15. Alan

    Excellent prompt service and a good courier- no damage to package and strimmer working as expected .
