Yale V-8V001-GL Wide Angle Door Viewer, Fits Doors 25 mm to 59 mm Thick, Polished Brass Finish, Standard Security, Visi Packed, Suitable for External Wooden Doors

This cost me £24, being a Yale product I expected it to be a quality product, instead you get three threaded brass tubes and two plastic lenses. Image quality is poor. Take my advice, don't waste your money on this item.

Great - just what I wanted

Having had a Chubb Door viewer in my old front door which gave a very good clear view and lasted years - when I replaced the door I looked for a replacement Chubb viewer. On the surface this looked like the old viewer. But on installing it I found the view was unclear. I took it apart and found that the PLASTIC lenses had manufacturing tabs which had not been removed - this meant the lenses did not seat correctly - leading to the poor view. I filed off the tabs and reassembled. Viewer now works but is no where near as clear as my old chubb viewer. Not the Quality I would expect from Chubb

Perfect
