ok so I tested the machine out on thicker/harder material like spandex and sequins and it worked out great only if the battery was above half life. Once the battery was past that it tore the fabric up. I ended up just charging it fully and then kept it plugged in when I was doing a bunch of thicker fabric. Also the glue that it comes with only works well for 1 cut to hold the fabric down so I would def suggest getting the spray adhesive with this. Thats if you decide to get it lol. Other wise it works great and is really easy to use.
