About this CompanyScience behind Portable Water Purifier
We have run meticulous laboratory tests to ensure our UV Light in our portable water purifier makes water from ANY source (free of debris) 100% safe to drink. See the full lab report here.
CrazyCap uses advanced 278nm deep UV LED to effectively sterilize water. See the charts above showing a significant reduction of bacteria in the contaminated water in both Normal and Crazy Mode Sterilization. The spectrum (260nm to 280nm) of light is found to have maximum disinfection capability.
Thanks to the recent development in LED technology, this special spectrum of light can now be produced without using toxic Mercury. When the Deep UV light enters the microbial cell, it destroys the active core (nucleic acids). Cells without the active core will no longer be viable.

This is the third cap we have owned...

I finally went on a couple of hours hike so I could test my new CrazyCap PRO. I'm already familiar with the CrazyCap2 (that I love), now let's test the PRO. 1) I love the fact that it won't turn on unless it's completely screwed on the bottle. No chance to get some UV rays in the eyes. 2) The fit is perfect with the older bottle 3) It might be because it's newer but I felt that the battery lasts a bit longer than the CrazyCap2 ? This is not verified however. About efficiency, well I'm not a scientist but what I know is that I am VERY sensitive to bad water. My stomach does not tolerate unclean water at all. Even tap water from rural town can sometimes make me sick, that's why the CrazyCap is so important to me. With the new PRO, I've never felt any stomach pain even after drinking more than 2 liters of water from a stream and a small river. I can really say that CrazyCap Pro is THE easiest and safest way to drink water in the wild. Depending on the time you spend in the wild and on how often you use the CrazyCap, it might be a good idea to bring the included charger with you. Since it's a USB plug, a power bank or a small solar panel is perfect to recharge the CrazyCap.

I’m bought this cap as a replacement for one I got a couple years ago. I’m always said it was the favorite purchase I made. It really makes all the difference with the water I drink. It was a painful time waiting for this new cap, and I’m overjoyed to have a clean bottle again

Overall I love the product and it works great. There’s only some improvements to be done to be excellent: - Sometimes the sensor bc is a touch sensor, it doesn’t detect it perfectly. - Charger is really bulky and there’s no option for USB-C. - A little bit expensive. I paid it because there’s no alternative on just caps and love the vision and want to support the founder to continue working on this.

This purchase is my third CrazyCap, the other two are the CrazyCap2 model. I use them daily at work and at home.

Thanks to CrazyCap, I finally drink enough water.

It’s a bit more complicated but if you’re familiar with the original Crazy Cap or the Crazy Cap 2. It’s not hard to catch on. (Hold for auto cycle,1 tap for power check, 2 taps for normal mode, 3 taps for crazy mode and 5 for drink remind.) Happy hydrating

Delivers on time.
Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
