Way too “lekker” tasty
Being from South Africa I’m skeptical on US made dried meat products - BUT these are the real thing.
Difficult not to eat the entire pack in one session. Major discipline required to put it down.
Great products.

Very satisfied!
Heard about Biltong from one of the youtubers I watch, and wanted to try it. This is delicious, much more so than your regular beef jerky. I have tried other brands, but this one is by far my favorite for the flavor and texture.

Quality biltong
Biltong is the beef jerky i grew up eating… so nothing else really compares. These people do a bang up job. Expensive but worth it as a treat or a gift for someone who likes quality jerky without all the extra preservatives.

Arrived opened/tampered
My pack arrived late AND was already opened. Considering this is food, I'm not sure if this is even safe to eat.
A real shame since I was really looking forward to having some good biltong.
