they are accurate tho fenster, I have the hardest punch in benidorm using one of them punch bag machines

in a pub in the middle of benidorm with loads of fellas having a go at this punch bag machine, all taking massive run ups and that

i stood in front of it and put my fist right through it with an overhand right, feet planted to the grown with a twist of the hips I beat the top score by a considerable margin

now im not bragging or anything im just saying that they must be pretty accurate
