About Me

Jeremiah Kowalski — Drinkware Product Researcher & Reviewer

I research, test, and analyze drinkware products, with a primary focus on reusable water bottles, tumblers, and insulated drinkware. My work is dedicated to helping people choose safe, functional, and durable products for everyday hydration, based on real-world use and careful evaluation rather than marketing claims.

 

I personally own and have tested 100+ drinkware products, including bottles, tumblers, mugs, and filtration systems from brands such as Hydro Flask, Owala, Stanley, YETI, BruMate, HydroJug and more.

Why This Blog Exists

These days, finding a physical product review written by a real person feels harder than it should. You don’t need a study to see it. Spend a bit of time browsing product reviews online and the pattern becomes obvious: generic claims, stock-looking images, no real testing, no proof that the writer has even touched the product.

 

And in my opinion, that’s a terrible direction for the internet.

 

Water Bottle Advisor was created partly as a response to this flood of AI-style reviews. Back in 2023, I was trying to learn more about hydrogen water bottles and wanted to find a proper review written by someone who actually owned the bottle they were talking about. Not a rewritten product description. Not a list of specs dressed up as “experience”. A real review.

 

I couldn’t find much.

 

That’s when the idea for this blog started to take shape. I wanted to build a water bottle review site where things are done differently. Every product I review is something I bought, tested myself, and photographed in real life. Simple idea, right? It should be the standard for every review blog. Sadly, it’s becoming harder and harder to come across.

 

The most important rule here is simple:

AI does not replace real testing, real photos, or real opinions on this blog.

Every opinion you read here comes from my own experience with the product. Sometimes that means using a bottle for weeks. Sometimes months. In some cases, years. I don’t want to guess how something performs after reading the product page. I want to know how it holds up in normal daily use.

 

The photos are mine too. They are not AI-generated, and I reserve the copyright to them. You’ll usually see the Water Bottle Advisor watermark in the bottom-left corner as confirmation that the photo comes from my own testing.

How I Test Drinkware Products

Water bottles may look inconspicuous, but once you start reviewing them properly, you quickly realize there’s a lot more to them than “does it hold water?”

 

First of all, I follow one non-negotiable rule:

If I don’t personally own and use a product, I don’t review it.

When I get my hands on the product, I look at:

 

  • durability,
  • insulation,
  • ease of cleaning,
  • portability,
  • lid design,
  • drinking comfort,
  • weight & height,
  • base diameter,
  • cup holder compatibility,
  • and whether the bottle is easy to carry around.

I also check smaller details that many people don’t think about at first, like the quality of the powder coating, how comfortable the handle or loop feels, whether the bottle is awkward to open, and if the lids are interchangeable with other lids from the same brand.

 

Those small things matter. A bottle can look great online and still be annoying to use every day.

 

Some products are even more complicated. Hydrogen water bottles, for example, need a much closer look at hydrogen production, membrane quality, hydrogen output, cleaning, warranty, and brand reputation. Smart bottles add another layer, because then I also need to check the app, reminders, battery life, setup process, and whether the “smart” features are actually useful or just there for show.

 

As buyers, we don’t always think about all these details before ordering a bottle. But they can decide whether you enjoy using the product or end up leaving it in a cabinet after a week. That’s why I pay close attention to the little things and test each product as thoroughly as I can.

How This Blog Makes Money

Some links on this blog may be affiliate links. That means I may earn a small commission if you buy through them, at no extra cost to you.

 

This does not mean I’m sponsored by the brand selling the product. If I include an affiliate link to a specific bottle, it simply means I tested that product and consider it good enough to show you where you can buy it.

 

Affiliate links do not decide my opinions. If a bottle has flaws, I’ll mention them. If I don’t like something, I won’t pretend otherwise just because there’s a commission involved. That would be a short-term way to lose long-term trust, and that’s not how I want to run this blog.

What I Don’t Do

  • I don’t publish reviews of bottles I haven’t used.
  • I don’t use AI-generated product photos.
  • I don’t copy manufacturer claims and present them as my own testing.
  • I don’t recommend a bottle just because it has an affiliate program.
  • I don’t hide major flaws to make a product sound better than it is.

And I don’t want this blog to become another place full of vague, copy-paste reviews that sound nice but don’t help you make a better decision.

Environmental Responsibility

I care deeply about sustainability – not as a slogan, but as a practice.

 

I am a tester, not a collector. I don’t keep bottles as trophies. Once a review is complete, if a product does not serve a specific long-term testing purpose, it is re-homed. Over 90% of past review units have been donated to friends, colleagues, and family members.

 

My goal is simple: every bottle I review should go on to replace thousands of single-use plastic bottles in someone’s daily routine, rather than gathering dust on a shelf.

Corrections & Updates

Products change. Brands redesign lids, update materials, change safety statements, release new versions, or discontinue certain models. When I notice that something important has changed, I update the article.

 

I also try to keep my reviews and buying guides as accurate as possible, but I’m still human. If you spot an error, outdated information, or something that needs clarification, feel free to reach out. I’d rather correct a mistake than leave readers with information that is no longer useful.

Help Keep This Blog Going

My goal is to make this blog feel like a breath of fresh air in a room full of copy-paste reviews. AI fatigue is real, and I’ve felt it myself.

 

If you like what I’m doing here and this blog helped you make a better purchase decision, there are two simple ways to support it. The first is adding Water Bottle Advisor to your bookmarks. It helps more than you might think, because it sends a signal to search engines that this site is useful.

 

The second, and by far the biggest help, is buying a product through one of my affiliate links. It costs you nothing extra, but it helps immensely with running this blog and covering the cost of buying products for future reviews.
