It punches right through hard plastic sleeves that I put my literature in for retail P.O.P. racks. The last one I bought could not do the job it just wasn't built that good.
I've punched about 3 holes with it. Still working -- how's that for durability? No I would not recommend to anyone. I do not recommend hole punches to people. No batteries included. Of course it doesn't need any batteries. But still.
