What are the main features of the Flymo Mighti Mo 300Li cordless mower?

This simple cordless mower can mow for 25 minutes, covering an area of lawn 250m² on a single battery charge. The battery takes 120 minutes to fully charge. It has five heights of cut ranging from 25mm-65mm and a 30L plastic grass box. The safety plug needs switching on rather than just slotting in for added security and there's a spare safety plug, which is very handy. The battery and charger are included in the price.

What is Flymo Mighti Mo 300Li cordless mower like to use?

The assembly instructions are simple but it also has a very intuitive design so putting this mower together was quick and easy. The only issue was the plastic grass box. These are often tricky to snap together and this one was no exception. The lid to the battery compartment is quite stiff and it’s difficult to get the batteries in and out. Changing the height of cut is easy, with a central lever. The grass box slots on and off smoothly and the mower is very light to carry around, using the handle. It's also very quiet, at 85.6 dB.

Is the Flymo Mighti Mo 300Li cordless mower easy to store?

The handle folds down easily to just the size of the body of the mower, so it can be tucked into a corner. It's also light enough to lift on to a shelf, using the central carry handle.

Is the Flymo Mighti Mo 300Li cordless mower good value for money?

Light and easy to use, once the grass box has been put together, this simple mower costs less than £200 and with a two-year warranty is excellent value for money. Replacement blades are also available to help prolong its life.

Who is the Flymo Mighti Mo 300Li cordless mower most useful to?

Best for gardeners with a small lawn, little storage space and for those gardeners with limited strength or mobility.
