You pay a bit more but it may keep your mechanic happy that they are installing a part that is less likely to result in you coming back with a gripe of some kind. Both my mechanics recommended this product over other options available.

Good workhorse piece of kit with good battery system range
Lightweight for the width of cut it offers. Efficient on battery life. Can tackle most lawn maintenance jobs. Grass box is rigid so storage of such a capacious box may be an issue for some. Manages its blade speed between two pre-sets based on the resistance it is encountering. Best not stored in damp conditions with variable temperatures as moisture can condensate on the motors central shaft causing corrosion within the motor. Post 2020 versions may have a revised motor design that may reduce this risk. Height adjustment is easy and it does not jump out of set position like some mowers do.
