"This is an excellent 'user friendly' product, enabling full drawer visibility when extended, with the added ability to easily remove the drawer if necessary. Other reviews helped the decision to select this item, but it would have hastened the decision if the Screwfix description had said it was a double extension runner, with only about 13mm overall thickness."
"These take less time to install than the cheaper plastic rollers (and much less time than routing a groove and having the drawer slide on a piece of wood or even a purpose-made plastic rail), they are more solid, and the work much more smoothly. They don't self-close, but they catch a little when they are full in, holding the drawer closed. The drawer can be removed completely with ease. The fixings are not included, but they take either regular screws (not too big, or they won't fit through!) or small drawer rail screws."
"These runners are quiet and smooth running, and provided the right length of runner is fitted, give access to the farthest back corners of the drawer, the whole drawer will extend to the front of the cabinet, which is great when your favourite pen has gone missing, and they are easily removable using the disconnect lever. They are very easy to fit, but as in all jobs of this kind, need a certain amount of accuracy when fitting to ensure easy operation, they are supplied lightly greased and packed in pairs in cellophane bags, and will give many years of frequent use, I have used them before and I will certainly use them again when the need arises, I fitted this particular purchase of runners to my own three office desk drawers, very highly recommended."
