Product review (5 stars): Even I could install it!  Husband not required. :)
Our Sinkmaster disposal replacement splashguard was so super easy to install.  (The old one was so worn it would pop out when we turned on the disposal.)  I took the old splash guard out and pressed the new one into place.  It took some pressure to get it into place, which was a good thing, since that meant it would stay there when in service.  Great product, great service!
