Cordless HYM40Li420P the right choice for me
I needed to replace my pull start petrol mower with one that my wife and I could use. After much deliberation I settled on this Hyundai cordless mower at a very competitive price. Hyundai kept me regularly informed of delivery details and the machine arrived safely and well packed a couple of days after ordering. The mower was easy to assemble and everything about the machine oozed quality and a chunky solidness, even down to the battery and charger. I was delighted!
After a full charge I used the mower on my wet, overgrown medium sized lawn. It coped effortlessly and well within one battery charge. The mower operated very quietly, and even though the grass was really wet the mower had sufficient power to fill the grass collection box fully without leaving a trail of cuttings on the lawn. Excellent product and service from Hyundai.
