I had one of these, and it was a pretty good machine while it lasted.
It has a very small harp, so difficult to use for quilting. I managed to quilt a twin size on it, but anything larger would be really difficult.
It's extremely lightweight, which is good and bad. It scooted away from me when I was sewing, so I had to put a mat underneath it. Lightweight means very portable, but it also means a lot of plastic innards, which isn't great for longevity.
I gave the machine to my niece and nephew to learn how to sew with, after I'd had it about a year and realized I needed a better machine. They used it for about another year, but now it is having computer problems. You can turn it on and sew a seam, but as soon as you stop sewing the first time it gives an error. You can turn it off and back on to clear the error and sew another seam, but as soon as you stop again, you get the error back. MECHANICALLY the machine is still fine - it sews great for that first seam, but that computer problem makes it nearly useless. It's such a cheap machine, it's not really worth repairing. I'm probably going to buy them a simple vintage machine to replace it.
So I'd say it's an acceptable backup machine for piecing or for a beginner, but not great as a primary machine for a quilter, and I wouldn't really expect it to last more than 5 or 6 years tops - less if you get a buggy computer like mine apparently has.
