Our verdict
The Murray MRD300 is a 'first lawnmower' — a tenant's mower for a small front lawn, or the spare you keep at the holiday cottage. It's not built to last but it costs less than a tank of petrol for a Honda. For a flat lawn under 200m² and no ambition for stripes, it's enough. Anyone with a real garden should look at the Bosch Rotak 32 instead.

Buying second-hand
Used MRD300s are £25-50 because the next owner usually upgrades within a year. The induction motor itself almost never fails — the failures are cracked decks and severed mains cables. Bring a 13A test plug and try it on the seller's lawn. If the cable has been spliced or repaired with electrical tape, walk away — that's a fire risk.
