Review: Rollers for Beko fridge-freezer

Ordered these as being specifically suitable for a Beko product, in part because the spec for the fridge-freezer made no mention of having rollers. Upon delivery of the fridge-freezer, it became clear that there were rear rollers. Furthermore, the delivery company said that the rollers I had purchased were unstable. I tried to use the rollers. By adjusting the front feet of the fridge-freezer, it was stable. However, this was only by raising the front of the fridge-freezer. Resetting to level, the rollers became unstable and I removed them. I achieved satisfactory stability without them. The rollers may be useful on occasions to relocate the fridge-freezer, but that is all.
