Great price!
Color: Silver
For the price I'm extremely happy with this juicer! Easy to clean! I will say it's a little difficult to make large batches with this juicer. I just keep a pitcher beside me and dump the container when it gets full. I do find myself cleaning the grater a few times while I'm juicing because it does tend to get clogged. If you're new at juicing and want to try it...get this! Totally worth it! Gets the job done. I've used mine several times so far, but still can't see myself paying $300+ for a juicer.
