Okay so the unit works as advertised add some dishwashing liquid for anything with a large build up of dirt Diamond ring came up nice and sparkling again sterling silver jewellery got its brilliant shine back reading glasses came up clean with no dirt or smudges left on the lenses. All in all for cleaning home jewellery and other smaller items it is great value for money only thing that annoys me with crazy sales is their courier. Fast way couriers dont have point to point scanningtracking. So untill the goods are onboard for delivery you have no idea where your order is or when it will arrive given all the major couriers usually have point to point scanning with an estimated time of arrival Fastway Couriers is outdated and does not provide a service that falls inline with most online shoppers expectations
