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.

It is exactly as described. Very happy with my purchase and consider buying one of the other caps as well.

Taking it backing on the Camino de Santiago! Peace of mind for my trip. I really feel like it makes our well water taste better too! I love it! Would highly recommend it to others!

I purchased the original cap and bottle for my son a year ago. He uses it every day. The rechargeable battery in the cap lasts only one year. These are replacement caps.

The CrazyCap 2 (Cap Only) did not fit my CrazyCap bottle. But customer service was nice and they are sending me a new one.

On the website, it says that these caps for in other bottles, like S’well, it it doesn’t say that it only fits the 17oz bottles, not the 25oz. So I have a S’well bottle that the Crazy Cap won’t fit on. (Bottle was personalized so I can’t return). I would’ve ordered bottle with Crazy Cap but they only had 2 styles available in 25oz.

Ordered two caps to fit on SWELL bottles. They fit great. Charged the first one and it was green and then placed on my bottle and tapped...nothing; no LED lights; tried to tap again and nothing; tried charging again...nothing. Tried the other Cap....same thing. I thought I was doing something wrong so i emailed CC and they sent some videos; I was doing everything that I was supposed to; not sure if I just got two duds but Crazy Cap requested that I send in a video to share, which I did and have not heard back; i will probably just ask for my money back and return these. Disappointing. Seems like a good product and was looking forward to cleaning tap water for better taste. Too bad

A mark of a quality company is it's customer service. I ordered a CrazyCap and upon delivery it wasn't working. I immediately contacted the company and they were very responsive! They chatted with me, no wait. Verified the issue quickly and immediately sent a replacement which works great!!! It is possible for any company to have an occasional product issue, how they handle it is important. They have won my loyalty!

Awesome way to use the Swell bottles we already have in the house by getting a few crazy caps.
Kathy P - 05/17/2021
Love my crazy cap! Charge it at night, then use it in the morning. What I would really like is a crazy cap that also works like the swell sipping cap. All in one. That would be the ideal situation and one I would purchase for friends & family members! Get busy! Btw, my daughter is Dir. of Hazordous Waste, Environmental Dept. at a nearby university. She is greatly interested & impressed with Crazy Cap.

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.
