Should be read as in other reviews, it is a quality lawn edge. The material is stable and not limp. Before diesm background also a very good price-performance ratio. The fact that the brackets between the individual tracks can solve during impaction is the case indeed. In any case, it is not advisable to put the rails by simply hammering in my view. Due to a quite hard ground, it was necessary to prepare for me the course of the rails, so that I could use the rails in principle in a gutter and subsequently replenish with earth. This approach has very reinforced, so I can generally recommend. The rails can be personalized with some force also good bend to form corners. Tails you can order the desired length according to the supplier, but I just cut the last rail using a saw. The result is super. Overall I would recommend the lawn edge, it forms a great completion of the lawn.
