Ive noticed that one the [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] it has 3 marks on the bars each representing different tension. I am not able to push past the second set of marks. Im not saying im trying to put that much tension on at all but with the device on the table the springs/tension stop at the second set of marks. Is there a reason for this or did i get a faulty device?
