Based on 9 reviews

Absolutely delighted with this mower. Easy to start, powerful motor makes mowing large lawn a pleasure. Adjustable speed , plenty of room in the catcher. Worth every penny

Jacqueline Unthank
Great Mower

I am delighted with this mower. This mower deals with my large garden easily. The self propulsion and electric start are great.

Lynn Bell

When we moved to our new home with a larger garden, I decided to upgrade from electric cabled mowers and ordered one on Wednesday. To my delight, it arrived the very next day! After some confusion with the instructions (they didn't match the mower, asking me to press buttons that weren't even there), I got to use it today and it was a breeze to mow our 1200sqm garden! Before, it would take me a laborious 3 hours to mow the front section alone, but with this mower it was done in only 15 minutes - I'm beyond impressed!

Carmel Lambert
Brilliant lawn mower

Simple to construct, attractive, really silent and began with the first tug. Cuts wonderfully. Has a genuine sense of quality and is substantial. Electric start is a great extra.

Mohammed Malik
Very very pleased

I did a lot of research before ordering this machine online on Wednesday at 15:00hrs and took note of all reviews (good and bad). Upon delivery on Thursday at 12:30hrs, I was impressed with the build quality. As I had a limited time to report any defects or missing items, I didn't have a chance to charge the battery. After filling with oil and petrol, I manually turned the engine over a couple of times to lubricate the bearings and it started on the first attempt. I then tried the electric start and it started again instantly. I have only used it for two and a half hours so it is difficult to assess its longevity, but so far I am very pleased with my purchase.
