Taunton GB Old Tauntonian
Efficient cut, easy and light to manouvre, so far ( only used it twice) clears up ALL cuttings as it goes. Battery JUST lasts for cutting 95 sq.m on a high cut (number 4, leaving grass about 2 inches long)
Battery life adequate on a high cut setting (4) covering about 95 sq.m. Any lower and you do need both the batteries supplied as the machine is working a little harder.
NOT supplied with quick release handles as advertised which makes folding for storage a pain !
