Good day to you. I would like to have a few questions answered and hope for your help. I see a price difference between the three colours that is not clearly visible. It is obvious that the weight of the packaging is different. For red 4.0 kg, for white 5.28 kg and for green 5.0 kg. This raises the question of whether the accessories could be different. I also wonder about the manufacturer's warranty for spare parts. I feel it is important to have these questions answered before making a purchase. Thank you very much for your feedback.
