Review on Grommet Machine 1500Pcs Grommets Posters by Johnny Pigao

I am very familiar with how the upholstery tool works and this tool has been rated as heavy duty, it can go through skin but it cannot even go through two layers of sail material. Very disappointed. I use the largest bushing (1/2" center) and it never seals fully. When my 28 year old son used it he couldn't get the bushings to fully seal either. Very disappointing. Not a good buy at all.
