Review on 🚰 Flexible Double Kitchen Sink P-trap - EASYDRAIN Ref. 505 with Expandable 1-½" Diameter, 2 Female Threaded Nuts, and 4 Wall Drain Size Options: DN38, DN40, DN48, DN50 by Matt Chirila

"S3 Female Nuts on All 3 Sides" Reason for return. Made in Brazil, which explains the futility. The screws at the top look like a standard 1.5 inch drain pipe. The bottom end is nothing. No screws. No nuts. An electrician's knife for cutting makes it impossible to easily install the flexible drain pipe. The size marked DN40 is too large for a standard 1.5 inch drain size. He cannot enter. The size marked DN38 is slightly smaller than the retail size 1.5". The stock gasket will be a little loose so it will definitely leak. I don't have a coupler on hand and don't want to use PVC glue again.
