      Slimy! Taste okay, but strange texture
      Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12), Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
      I really wanted to like these but they're really slimy! I've had Jack Links before but these are even more slimy. I normally get chomps or archer beef sticks. I would say these have the texture of the archer beef stick just a bit more slimy. Not my favorite.

      Great for snacking!
      Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
      Being a diabetic I enjoy eating these for a snack because they won’t raise your blood sugar. Taste is fine and an excellent source of protein.

      Gross Texture - Weirdly Soft
      Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
      These are literally the nastiest possible version of a meat stick I've ever had. Bought them for the price and for lunches to take to work. As it would turn out, I couldn't give them away to family. Everyone who bravely tried it were met with the same gross, weirdly soft, texture. No matter if it was refrigerated or room temp - it was eerily soft I felt like I was eating baby food. The flavor was... Fine? I guess. It didn't wow me either way, just kinda existed. They are also pretty small, I expected more than 4in per item for the price. I thought the price was good when I thought they were bigger, but when I discovered they were smaller, the price became less worth it. Overall, I'm not sure who the target audience for these it because adults and kids alike did not like them or their weird texture.

      Good 😊
      Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
      I’d rather reviews on these before purchasing them and I didn’t think I was gonna like it. I seen a lot of bad reviews lotta negativity, but I was impressed. They’re actually good a little greasy not too much. They were not mushy at all. Remind me of a slim gym, but not that greasy. I normally eat a different brand, but I really like this and I will buy it again. I recommend it. I wasn’t going to try it because a lot of the reviews weren’t too good that I was reading but they’re good. I like them, but I’m glad I tried it and they are zero sugar.
