I used a service about a year ago - no need for a box or any external usb stick, i just downloaded an IPTV app from the LG store. It basically had everything, including loads of grot channels which probably isn’t ideal if you have young kids.
It was good but it’s a constant game of cat and mouse with these providers. Alot of them are reselling content from the same sources and they do get busted quite often.
Also I wasn’t really to comfortable paying for it with a card considering you’re dealing with organised crims.
