More like baby powder scent rather than honey
While this works well and is very moisturizing, the smell is awful. It does not taste or smell like honey at all. It smells like a really strong baby powder, and not a pleasant one. I couldn't even use it just on my hands because the smell was so strong. Instead, I've been using it on my rough feet before putting socks on, so at least it's good for that and I don't continue to smell it. I'm willing to try one of the other scents though, as they have much better reviews.

Great but large to carry around
This is a great product, and having beef cattle, I like to support other farmers. The ONLY thing I would suggest is to make it in smaller tubes so that it is easier to carry around. It is hard to carry in a jean pocket because of how large it is, so it makes it look odd and is awkward. However, that being said, I do use this for dry spots for winter skin, etc. Let me know when you make these in smaller tubes - I look forward to buying more and supporting your 'USA made' business!

Good
This thing is huge which makes it a little weird to use. It feels nice to put on, but then once it is on it feels kinda waxy I’m not really a fan. It also has a not super pleasant (in my opinion) scent. However, it lasts a long time as long as you’re not eating/drinking and it does meek moisturizing
