It is not heavy, it is not suitable for office use, do not buy it if you want to work with one hand, it does not work. To cut the tape, you have to hold it with both hands

Very good base. Heavy and sturdy with a nice rubber-foam on the base that sticks to the surface. So when you pull the Sellotape, you don't take it with you like other ones I had that require two hands to use. Simply amazing!
