The plastic that exists came off with the first use, resulting in scratching the steering wheel.
I had ordered 3 for others and we all had the same problem.
The construction is average, I believe that if someone wants to break it, they can easily.

Unfortunately, it scratched my steering wheel the first time, as it had an additional plastic attachment to fit on thin steering wheels, I removed it and it fits now, but still with difficulty (Nissan Pulsar). In the long run, it will further wear out the leather of the steering wheel... luckily I had sewn it myself and know how to replace it. I would probably choose one with a different fit. Honestly, now, does it fit in modern cars where the steering wheels have thickness at their rim, I don't know.

Economical and prevents the other person in the first place. It just needs a little adjustment in placement to avoid scratching the steering wheel

Very good, almost untouched, it just leaves a mark on the leather steering wheel! However, if you remove the inner plastic that acts as a protective, the space increases and it doesn't leave any marks on the steering wheel.

It goes in and out easily, but the protective cover is hard plastic and I'm afraid it will scratch the steering wheel with frequent use. I'm not an expert in protection, but it definitely functions preventively to some extent.

Very good, I have been using it for 2 years now. It has a sturdy construction and fits perfectly in both Opel Corsa and VW Polo cars

For the reliability regarding its durability and resistance, I cannot express an opinion (there are experts, but don't expect a review). As for its use after the second use (at first, you go searching), it is easily placed.
