they look good, i can tell you that. they say it holds up well. i used on interior so itll prob last for a while. as for which i got, i think it was the m500. im not 100% tho. i know it was their brand. they will send you a small sample of vinyl i believe if you want. call em up and tell them what you plan to use the vinyl on. then tell them your not sure which you want and if you can get some samples so you can decide. i believe they are open tomorrow.
also untill jan 31 you can use this, 10% OFF All vinyl products. Coupon code ( winter10 ). its on their fb page if you go like them , you can see pics of applications, and deals when they offer them
