My Polish is not very good so I'm posting in English. You can check the laptop in person before buying it.

MONSTER TULPAR T5 V14.1 Gaming Laptop
Intel Kaby lake Core i7-7700HQ
NVIDIA GTX-1060 6GB
8GB RAM
256GB+256GB SSD
15.6 Inch FHD IPS MAT LED

Everything works, no damage or repairs, with original charger.

Battery will not last very long, I always used it plugged-in with external monitor. Could maybe last up to 1 hour with basic usage.

There is slight screen burn towards lower left, only visible on light solid color backgrounds (pictured), on regular images or darker colors it is not visible to me. This happened because it was always used with the lid down while connected to an external monitor.

Fans are a bit noisy, requires cleaning for that, but works fine as is.

Only in person pick-up in central Wroclaw, I can also consider shipping but then I can't accept returns.
