Being quite satisfied with the Sonax 417700 synthetic leather, I wanted to try the synthetic cloth from the Extreme series, considering it the best and most advanced.

Negatives:
1) The cloth is not soft enough, resulting in poor contact with surfaces, leaving marks and requiring a second pass.
2) It is quite large, and whatever time you save in cleaning a large surface of the car, you lose in its not very user-friendly wringing.
3) In the lower parts of the car, the cloth can easily slide on the ground and get dirty, with the risk of small debris causing scratches on the next pass.

Positives:
1) The only positive aspect I found is its storage case, which allows the cloth to maintain a relative humidity without drying out until the next use, especially during the summer months.

Overall, I was not satisfied, and I would not recommend it, especially considering its price. My next purchase will likely be a towel from another company, hoping to address the aforementioned disadvantages.

I bought it as soon as it arrived in Greece, thinking it was something revolutionary. It didn't impress me, too much unnecessary cleaning and excessively large size...
