Strengths it might not be the most powerfull but it can hold its on. this thing can really take a beating and keep ticking. you will get years of service out of case 1845c i don't know much about there new machines but i can say this machine has not giving me any major problems, maybe a wheel bearing and chain here and there, but overall its a dam good machine. probably the best case has made.

Weaknesses none

Overall excellent
