WMF Stainless Steel Jar Lid Opener - Defective Item. Purchased new approximately 3.5 years ago and used about 10 times. However, one of the three catch points on the back came off when opening a lid, and it has become loose since then (see image 4). Also, the screw at the base of the handle is protruding (see image 5). Because the relevant part (image 4) is prone to coming off during use, it is recommended for purchase by those who can make adjustments themselves. The following is an excerpt: Product Description: After securing the lid with the black lever, use the principle of leverage to open the lid with minimal force. Usable sizes: Compatible with lids approximately 2.1 to 8.5 cm wide. Designer: WMF Atelier Material: Stainless steel (Cromargan®) Product Size (approx.): Length: 26.5 x Width: 10.5 x Height: 5 cm Product Weight (approx.): 335g Country of Origin: China (Designed in Germany)
