I went through a lot of options looking for POS software to sync local sales with Woocommerce stock, and this is the only one that did not introduce other problems along with it. It sounds with WC quickly and does not impact your stores performance or get bogged down waiting for your WC installation to respond. The barcode scanning sale feature works really well. I am hoping for a more customizable print setup in the future but the functionality is there. Unlike Square, the installation was painless and the sync feature works flawlessly. I recommend you refresh once the POS loads, as it sometimes has an issue with thumbnails being assigned to the wrong product on loading, but this is minor considering all of the ways that woo payments and square have failed to do what this plugin does. Patiently awaiting PayPal or square payment options but as is very much worthwhile.
