Here is a review from a customer who purchased this machine for heavy duty leather creations;

SMA TW3 441 customerPerrett 

One of the best machines to say the least, ideal for what ever you are doing. Easy to adjust from sewing heavy duty leather to a wide range of sizes. I use this machine for making heavy Bronc halters but then also for making chaps which can be 3mm, so I've really found this sewing machine great for leather of all thickness as well as canvas. The long arm allows heaps of room for movement and turning your object around. SMA hooked it up with a servo motor which makes it great for sewing at slow speed for those jobs with heaps of corners or going at high speed for straight sewing jobs. I highly recommend using SMA for sourcing your next sewing machine. Very great and friendly service and if you ever need to know anything or have any problems they are more than happy to help. Thank you so much Sewing Machines Australia.
