I just sold mine I got sick of changing the brushes but I shoot alot. I shoot 4 times a week around 200 arrows a day and the brushes do not hold up , the manufacturer was saying that the brushes could be too tight and it was operator error.
So I said ok I will loosen these bad boys up really loose well the brushes still wore our. for me its not worth messign with the brushes all the time , I switch to the Limb Driver and I dont have to worry about the wear . It looks cool and is very light and might be for someone that doesnt shoot but a few times a week and maybe shoots 60 arrows but for me and anyone that shoots alot I do not recommend it
