I had an extremely unpleasant incident with this product. I bought the Superior Balance 110lb digital bow scale. I bought a brand spanking new bow and a lot of accessories to set up my dream hunting bow - for which I have been waiting for 6 months, looking forward to the hunting season which is starting in May in Namibia where I live. On starting to set up my new bow, I first checked the pounds with the scale. Then I adjusted the bow to 70 lb and on checking the second time, the top ring on the scale pulled off - which lead to an unwanted dry fire and breaking my cam and ripping off the string and buss cable. I contacted Superior Balance to inform them about the incident and asked for reimbursement for my losses. The originally seemed keen to assist, but then they just stopped replying to my e-mails.
