I bought this 4 weeks ago and because it is Autumn, have used it only once. It needed minor assembly which was easy to do. Easy to use and cut/collected the grass well. Previous mower was petrol & 35 years old so looking forward to easy starting.

Having had bad experiences with the Ozito electric lawnmowers (the switches fail), I decided to take a gamble on the Massport. So far on a medium sided yard(988sq m) it has performed well-wide cut, easy to use, and battery only needs one charge to cut the entire yard. So far Id recommend it
Happy with purchase packaging was not to cumbersome
Mowed around 200 sq meter of Kaikuyi heavy lawn, still have a light showing on battery charge. Motor slows down when mowing height was too low. Sturdy build, large wheels all round. It is like a petrol mower with engine replaced with elec motor
This makes cutting the grass a breeze not having to worry about a cable to avoid , like a petrol mower only quieter . It will tackle any size grass not problem , though long grass drains battery quickly . Good quality machine , only gripe is battery only lasts long enough to cut front or back half not both ( 20 x 6 m lawns ).
