Customer Ratings & Reviews

I live near several state parks and great trails- I've often looked at the beautiful, clean-looking streams flowing through and thought about ALL the horrible things that I've told could happen to me if I just start drinking out of whatever random streams I find. Now I can!!

Since I don't have any lab equipment to verify whether bacteria are eliminated by the blue light in the cap, I can't tell you with any level of surety that this product works as advertised. I can tell you the led light on the top of cap will indicate that it's working, and I can tell you that the blue light inside the cap comes on. I can't tell you how much UV radiation is reaching the water in the bottom of the bottle or whether it's effective. I can tell you that neither setting (regular or "crazy" clean) is going to change the flavor of your tap water. It may (or may not) be purified, but it's going to taste the same.

The CrazyCap and associated bottle seem to be fairly solidly constructed and certainly work in terms of holding water or liquids for your enjoyment. And during testing, while I was able to put the cap into both included modes in terms of UV light, I have to say -- I have no idea if this is actually working. As a Technical Insider Network member, it most definitely is incumbent upon me to reach out to Best Buy, per se, when I need to follow up with a question or concern about the particular item under test. And, true to form, I was given additional contact information in order to forward my question/concerns to the CrazyCap company. Unfortunately, I didn't get a response regarding what happens if I were to take -- let's say, water from a mud puddle, or pond water, or some other potentially questionable water -- and put that water under this light, and be able to confidently tell whether or not the potential bacteria that could be in that liquid did, in fact, die. Frankly, I was told that the consumer would have to be a microbiologist to tell. In fact, I disagree. I do think that some semblance of a very basic litmus test strip could very well have been included with the product, at least for those of us that wanted some tangible evidence that water was truly being decontaminated and therefore would be potable (drinkable). I'm not saying that such a litmus test could stand up in court (in the event the company were to be sued), but if you're going to claim that water is going to become decontaminated by using this product, that really sounds like a promise to me, a promise that someone might really take you up on (I'm simply not inept enough to give that claim a test!). After all, was I holding the cap over the water bottle (or other areas like my smart phone or keyboard (which they also claim can be disinfected)) correctly? Was I holding it at the correct distance? And if I'm covering more than what's immediately underneath the light, how do I know that I don't have any "gaps" between the paths I might take, back and forth, to cover the area? And if this kind of disinfecting process is supposed to be performed a certain way, I would reasonably expect that the company would tell me so. At this point, someone who is reading this review might think I'm being overly paranoid; no, I don't believe in any chemtrail theories. But I think there's definitely a different perspective about this. We're "getting through" a particular viral pandemic, which I would think a product like this would be a God-send for some (assuming that UV light will destroy viruses as well, I don't know). Or, perhaps there are mothers out there who are legitimately concerned about their water, or maybe while camping or being outdoors, needed to use alternate sources of water, for whatever reason. How are they going to know that the water is truly safe? Since I simply cannot test whether or not the water has actually been disinfected without incurring the additional expense of getting lab work done to test, I'm going to have to pass on recommending this product to anyone. Again, while the design and engineering of the product appears to be top-notch, I cannot honestly tell someone that I was able to test my water, out of the box, and give any evidence that the UV light actually did anything to it.

I love this crazyCap. I feel better drinking UV treated water and in my small way I am helping our oceans by no longer drinking several plastic bottles of water a day and contributing to the plastic mass swirling around our oceans.
