ultra fast order reception assembly with good instructions, but a small problem because the sleeves of the arms did not fit into the holes of the arm due to the paint, it was necessary to re-drill the arm to remove the paint

Given the price and the advertising you do regarding the quality of your products, you could have included self-tapping wood screws for fixing the doors and rails. I therefore threw away your cheap screws for Parx self-tapping screws.
Translated reviews
Response from SLID’UP by Mantion
Hello Sir,
We understand your comment regarding the screws provided with your order.
However, the screws included in our kits are intended for use on wooden doors, in accordance with the assembly recommendations of our products. Unfortunately, we cannot provide screws suitable for all materials that may be used for making doors or supports.
Depending on the material and the configuration of the installation, it may therefore be necessary to use specific screws suitable for the relevant support.
Best regards,
The SLID'UP Customer Service

Mantion reduced the prices of the ordered items by 20% 3(!) days after receiving my order. I find this, to put it mildly, unfair! I would like a statement regarding this pricing policy!

Dear Dominic,
we are sorry to hear that you are dissatisfied with our service and had difficulties with your invoice. We understand your disappointment!
To avoid such (in this case: vacation-related) delays in email processing, we always send the invoice as an attachment upon receipt of payment, and the shipping notification also contains the invoice again.
Unfortunately, these emails occasionally end up in the spam folder and can therefore be easily overlooked. Sorry for that.
We hope that you are still satisfied with our products - perhaps we may welcome you again in our shop.
Best regards,
