These pliers "wobble" a bit, i.e. the loop is not as precise as it could be with comparable comfort pliers from Knipex like this one: https :/ /www. amazon.com/Knipex-2622200SBA-Angled-Pliers-Comfort/dp/B003RWS97Y/ But it is definitely sufficient for occasional use and the price is right. If you really need an accurate tool, spend the extra money and buy Knipex.
