Our verdict
A reasonable mid-range corded electric from a brand that actually has UK dealer support. Outclassed by Bosch on motor longevity but matched on cut quality. The 5-year warranty is worth £20 of the price.

Buying second-hand
£25–60 used. Cable damage and motor whine are the two checks. Cobra warranty is non-transferable so used buyers are on their own. Plastic deck cracks at the rear flap hinge — common fault, £15 part if you can find it.
