People confirm that they offer a great bang for the buck, especially in macros, compared to pricier protein bars. "I'm a gym bro. I take protein seriously. For the price, they are the best bars on the market," the person writes, noting that peanut butter and cookies and cream are their favorites. "180 calories for 21 grams of protein then 170 calories for 22 grams of protein. Honestly best macros available."

Some People Complain About Consistency

One of the biggest complaints shoppers have is with the consistency of the bars. "They seem to have a problem with consistency in production. Sometimes they are soft, sometimes hard as a rock. They've also been increasing in price recently. I've stopped buying them for now," one person writes. However, a handful of people claim to have a hack for their hardness: Throw them in the microwave. "Sometimes I'll nuke the rock hard ones a blip and they'll soften," one writes.

Another tells a story of how they would often bring food to give to the homeless every day. "I bought a box of these once and had to throw them away because I could not in good conscience let another human being eat them," they claim.

"My favorite is a chocolate chip cookie dough," added a third. There is one flavor that a few people aren't crazy about. "The cookies and cream version is what evil tastes like," another commented. "My husband is a human garbage disposal and doesn't even like those," another chimed in.

All of these 'low carb' things are loaded with sugar alcohols," another said. "My stomach absolutely cannot digest erythritol and I now avoid it after buying these," a third confirmed.

These protein bars are seriousl nostalgia-inducing, a handful of people maintain.

Definitely a unique texture though," another confirms.

While still a great value, several people commented they have gone up in price, starting at around $17 a few years ago. "I got them for $19 back in October. Now they're almost $22. One of the many Kirkland items that went up in price in recent times. Not as much as the EVOO though," one says.
