The quality of this product is not SPECTACULAR, but it is certainly adequate. Everything works as expected and it is great fun!! I would never want to do without this throttle quadrant after flying with them. Expect a very plastic product and you will be happy. I give 4 stars only because the interchangable handles can be difficult to remove sometimes and it feels like it may eventually damage the product. The handles feel kind of fragile so you will need to handle them with care. The price might seem a little high, but this is a specialty item. Buy them and start flying with them and I bet you will be happy :o)
