Because of the price but you have to make small concessions here as well, which should be clear. On the one hand the filler neck is secured only by a simple plastic cover, which is pushed in. Stable and secure is not, even if I so far had no problems. Secondly, the design is a little shaky with a few screws and thin metal. Since the ground but which does not matter and I do not use this type of garden equipment every week, I can certainly live with that. But who is looking for a lawn roller in long-term use, should probably be better access to more stable models.
Conclusion: The Einhell lawn roller has an unbeatable price / performance ratio for the casual user. Minor compromises have to be made in processing, which becomes the rare use but hardly noticeable.
