To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
First time i returned the tube due to its packaging. The tube is very delicate any hard bend will make the filament difficult to pass. Second time also received the tube in hard bends. Anyhow i tried to use it but then the OD is more than 4mm, never went in hotend. Total loss.
