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.
The item feels well-made without friction and with thick, high quality wires. However, there's really no way to look inside and see if it's actually a gold rotary or how durable the inner joint is. Time will tell whether this was a good buy, but I would have liked to be able to know beforehand.
