According to the informations from Beurer only for : BM 45, BM 49, BM 55, BM 75, BM 85

Indeed, the product "163.246" is completely out of stock, we do not sell it anymore (both on Galaxus and Digitec, it is the same company Digitec Galaxus AG, all the products on Digitec you find on Galaxus). Regarding the product "Item No. 236152" that you wish to purchase, the machete is delivered with the product. This item Beurer XL-Manschette (Arm) is not compatible with this product Beurer BM 58 (Arm)

Yes, I use them with a BM 58. They work perfectly, although they hurt a little in places. For the price, however, there is probably not much better.
