Seems like a lack of quality assurance.
Flavor Name: Lemon Pepper, Size: 2 Ounce (Pack of 8)
Honestly I purchased this after getting an amazing package at a specialty store in Houston and loved that there was the option of having a multi-pack and subscription on this. I was a bit reluctant bc of pics and reviews seen/read but took my chance and maybe there are just not consistent batches with the company. Not sure - but mine was gross and the one I had the other day was incredible from a store. This was scraps and full of fat and wouldn’t eat it and I can tell you so much fat that there is no way it would be 6g of fat for a bag. Quality control needs to be on. I don’t think I’ll buy this again. Sending it back.

Surprised
Flavor Name: Lemon Pepper, Size: 2 Ounce (Pack of 2)
It is very tasty. Would have score a five star except for the few pieces of indigestible fat added in the bag.

Amazing Beef Biltong with Some Delicious Fat!
If you enjoy beef biltong that is easy to eat and has a little delicious fat on it too, this biltong will make you very happy. It is pretty plain just with salt and does not have the typical coriander flavor. I did not find it overly salty and the slices keep well in the freezer or in a bag they supply with your order. It is a paper bag you are supposed to keep the leftovers in in the refrigerator. You can also freeze extra biltong for later and thaw it out in the refrigerator as I'm doing now. I have tried a lot of biltong in my lifetime and used to eat it in Africa on a regular basis. Now that I'm back in America I keep trying different biltong companies to see who is the best. This is in my top 10 of biltong experiences. You get a lot for your money and it is well worth ordering! ~The Rebecca Review
