        Great lip balm
        I have had chapped lips for most of my adult life. This product has been the first product that I have used, where my lips are not cracked, peeling or dry. There is no smell or taste, very neutral. I had to use the balm frequently in the beginning, now maybe only several times a day. One tube last a long time I highly recommend this lip balm.

        Just ok
        These are just simply too large to use as chapstick unless you do both top and bottom at the same time ( no thank you). I threw them away. 3 stars because it appears to be a good product, but they got the packaging all wrong to call it chap stick.

        Replaced Vaseline - Far superior product
        I received this as a gift a few months ago and it's all I use now. I use it on my lips and on my neck wrinkles. Do not leave it in a warm environment, like hot car or pants pockets, it will get very soft. If it does get soft, i just dab it on ranther than rolling/wiping on. Also its best to roll it down when not in use, but not necessary. I used to be addicted to Vaseline products for my lips and this is far superior in many ways.

        Not really good as a lip balm
        It is way too melty or liquidy when applying. It's like putting oil on your lips. No staying power. I actually ended using it more as a skin moisturizer like a lotion. It's pretty good for that. I haven't even tried taking it with me in my pocket as I think it'll turn to a liquid like coconut oil down here in sunny hot Florida. .
