(X-posting my review from amazon, only slightly edited:)
I received a sample of this in my Good Life voxbox, and I wanted to really like this product because I suffer from headaches and joint pain often, and a convenient on-the-go powder would be ideal, right? And in many ways, it is.
Just like it says, it is a small and convenient pouch, and you can fit them in your purse or backpack- you could even fit a couple of them in your wallet, or just your pocket. And, just like the product promises, you can take these powders without any liquid- just open the little package and swallow the powder like a pixie stick. And yes, it will relieve your pain- just as much as any aspirin/caffeine product, maybe a little faster for the sake of being a powder.
However, you have to remind yourself that this IS an aspirin powder, and despite the sweet lemon/lime flavor, you WILL be able to taste the aspirin. If you've ever chewed up an aspirin, or taken too long to swallow one down before, you know what it tastes like, and you know that the taste doesn't go away for a while. So, while the product does what it says, you can't fully mask the flavor of aspirin, and while you don't NEED liquid to take the powder, you'll probably want a drink to wash it down with.
Maybe you're thinking the taste is worth the convenience and the fast action, but let's talk about the price. 13 dollars for 12 single-dose packets of this. Eight dollars will buy you ~200 acetaminophen/aspirin/caffeine pills, or, if you don't want acetaminophen, you could get ~500 aspirin pills (which will be about 350 doses, if you want the same amount of aspirin as is in the UrgentRx powder) with that same eight dollars. Five dollars for a bottle of caffeine pills, if you want that as well. And you can chew any of these pills up for faster action, if you're willing to deal with the taste.
So, for the price, and considering the fact that you're probably going to want a drink anyway, you could do better. Giving this product a C for the fact that it does what it says, but the convenience does not outweigh the taste or the price of this product, and the fact of the matter is that there are better products out there for the price that are just as portable (pillboxes are a thing, or even just plastic bags if you really don't want to carry around a bottle of pills).
Unfortunately, this product is not for me, and I cannot say I will be purchasing it any time in the future. It's a good idea, but I feel that it is poorly implemented.
