I would not reccomend this bow sight as they are not very durable, I had 1 break after 1 week of usage and the manufufacturer gave me some lame excuse that I tightenend the front adj. screw to tight(I did not) and would not stand behind his product. I have had 2 other sights on my bow with no breakage from adjusting any screws. The Manufacturer did tell me that other people have also broken the sight and 1 person on more than 1 occasin. In my opinion there is a design flaw that makes the front Adjustment screw area very weak and prone to breakage.The Manufacturer will sell you a replacement part but why should a product break after 1 week of usage and then you have to buy a part to fix it and even if you do the same design flaw is still there. Do yourself a favor and buy a more durable sight for your bow. Also after the manufacturer would not send a part free of charge and I started to complain to PayPal and the B.B.B. he increased the charge for the replacement part from $20.00 to $40.00
