Excellent value for money. It arrived ready assembled and fitted perfectly working both as a plug and a strainer. The only problem was removing the blue protective film from round the spindle. I had taken care to measure the aperture before ordering.
If only this been available when I started researching, it would have saved me a great deal of time and effort in working out ways round problems. A well written guide to the methods of genealogical research, ideal for all those researching family history both beginners and experienced researchers.
