Our verdict
If you already own Parkside X20V tools, the PRMA 40-Li is a no-brainer addition that piggybacks on your existing battery investment. Standalone it's a fair 350m² cordless. Watch for the Specialbuy windows (typically March-April and August) when these appear at Lidl.
Pros & cons
Pros
- Parkside X20V battery family — shared across 100+ tools

- Brushless motor
Cons
- Uses 2x 20V batteries (not 40V single) — half the runtime feels
