5cm round brilliant i have this product for a while i had no problems with it does work fine and perform well on any angle i use i like where the switch button is placed and does not get heated i used to lay down some flashing band on the roof to light some bonfires and to light the bbq overall does the job good simple to use just what i wanted thanks does the job and no nonsense

Very good starts first timei use it at my allotment for cutting and burning holes in weedfabric it seals the ends of the fabric and stops fraying it only takes a second literally to make a hole 3ins 7
