these are lightweight stamped stainless units. they work well but sit much lower in the drains than the old ones .
there is absolutely nothing wrong with them as strainers / stoppers , but they feel so so. they come in 5 pieces each the top nut/ handle , the strainer , the rubber seal , the backup washer and the bottom strainer pin... you have to assemble them yourself.
but after using them for a bit , I decided to take them apart and just use the rubber seal to replace the ones on my old set. they fit exactly and I now have my originals in perfect working order.
so minus one star for the light weight feel of the units , and minus one star for having to assemble them.
