While some might find the upper size limit troublesome, I would rather it could go smaller. The only time I wished for more than the 4" max was in cutting out frames for some bigger pictures and I just did them the old fashioned way, with a xacto. As these are easy to cut that way I didn't see any reason for a bigger more costly machine at this time. The kit comes with everything you need to start right away. I mean right away as you don't have to wait for it to charge. The cord didn't get in my way at all. But if you want to travel it works for a long time cordless. All in all, more than good enough.
