Ordered two for my kitchen double sink. Although the waste insert fits perfectly in the 90mm sink opening that seems the only perfect bit. The two sets differ vastly, although they seem the same. Different size parts. One fits, one doesn't. One has plastic parts where other has metal parts. Both are rather flimsy. Bottom part to connect to rest of waste does not fit normal 40mm piping. One that fits I could manage to work without leakage. The other one is just a mess. Price is wonderful, but money wasted. Should have bought a better quality product. Will recommend this only to gamblers - you might get the good one. Won't buy again.
