Very good drawer guides.
For their price, they are extremely good.
They don't have brakes (slowing down), but they have very nice final stops and when they close, they "click" and keep the drawer closed.
Relatively easy installation, for someone who deals with household repairs.
They seem very sturdy.
They replace the classic guides with wheels, with a thickness of about 1.8cm to 2.0cm gap between the drawer and the fixed part

They were installed in heavy drawers, each weighing at least 25 kilograms with its contents. They work well and do not "hang" with the drawer in full extension. The sliding is relatively good. Very good for their price.

A regular drawer guide. It doesn't have installation instructions, so I had to search online to find them. For this reason, it could have a lower price. Its durability will be evident during its use.

They are cheap for their type but they are quite sturdy and roll quite well. For heavy drawers, for example, large toolboxes, I would recommend something of higher quality. However, for household applications, they are more than sufficient.
