I love the idea of these grips, but there are 3 major issues for which I suggest you save your money for a different product. 1. The grips came with notable black grease-like marks. When I had AircraftSpruce contact the merchant, they said that is normal for teakwood. Now, I wish I could upload an image, because all you need is to have at least one functioning eye to see that the black marks do not even follow the contours of the wood veins and are very obviously due to something having rubbed against the grip, depositing this black/greasy substance. Merchant responded that that is how teak is (!!) and thats it. I sent a couple more pictures, but I dont think they have eyes.. 2. The buttons are shown in all pictures to be one with a black dust cover and one red. Product was delivered with two black ones. When I inquired, I was told the red one was only for custom orders, the default is two black -- which is written.. well, nowhere, nor was there any option for it when I placed the order. So the pictures are NOT representative of the product, and you should use your psychic powers to know that. Again, seller just told me the above and told me to stop bugging them. 3. As you have probably inferred, their customer service is awful. Save your $299+$299 for something better.
