As my shower has a circular door glass cabin, I was for some time in search of a puller that fits precisely to this rounding. I now have it for a week and he does a good job. The puller is nice and light and can be grabbed and handled well despite its unusual shape. If he falls down a time you have to worry that he damaged the shower tray, as it has no metal components. The discs can be good pull and the rounding adapts very well of my cabin on. At the practical eyelet can hang him out to dry.
