i have not bought a v belt from a parts house since first discovering your service. your v belts are high quality and durable. i have used them on a wood mizer lt 40 bandsaw mill and have replaced the timing belts as well as all the belts on my wife's infinity and alsoon my ford f 150 that i just gave to my son. and gave him the new serpentine belt we just ordered and told him that for quality and savings to continue with your site. as i have never had any negative issue with your belts. regards chuck
