BRECIOUS Slow Masticating Juicer

This is my first juicer so not sure how it compares to others. But on its own, my take is that it looks and feels cheap. The body and all parts are plastic. It took a moment to figure out the assembly and dissembling necessary after each use. Are we to be wary of a product that comes with a plastic wrench because the parts are so hard to take apart for cleaning after each use? I find it funny that the manufacturer sends a wrench for that purpose, instead of improving the design. At first I thought I was getting a decent deal when it was on sale for sixty bucks, but I don’t think this juicer is worth that. I’m juicing wheat grass which is very soft and easy on the machine but even then sometimes the juicing part shakes a little too much while the grass is going through it. Also realized I need an abundant amount each time to yield a little juice. Same for carrots, it takes several carrots to fill half a glass, but I guess that’s just the nature of juicing? I take it other juicers will yield a similar amount? Still not sure if I wanna keep this. Having to twist a wrench to open the juicing part each time is a bit much.
