Science 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.

Got the 4D and the 32 oz bottle!

The creators have been the worst with communication and always over promised rather than underpromise. We have been left dangling months at a time with only an update every two-three months

Color codes for programming get a bit confusing. Should come with USB-to-Wall Outlet connection. Charging cap stays yellow no mater how long I leave it charging.

Very easy process!

This is the sturdiest I’ve ever owned. You’re not going to scratch this easily; and it’s well weighted so that it won’t simply tip over- full OR empty- when the wind blows. I trust it; it does what it says; and, it works well. Large enough to quench but small enough to carry on a backpack, slant bag or Loctote.

I am at your mercy as whether the water is clean or not. A regular meter does not detect everything but the TDS tester does not show any improvement.

Quickly found what I wanted, only problem was not enough bottles that hold larger amounts of water.

It took a long time to get the replacement and I'm not sure the replacement is working properly. Being able to just email would be easier than going through the website each time.

Kristina has been great and accommodating. I provided all relevant info about the order in the first email and she responded soon afterwards. She shipped both the cap and it's charger just in case both of mine were broken. Great experience overall.

It does make the water taste different. More neutral, I would say. Seems like this generation of products has a problem of charge capacity once the charge drops to 0, but the customer service for replacement was great.

Fast and easy to find what I needed.

All good
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.
