Chroma Keto Built-in Color Chart Ketone Testing Strips - Urinalysis of Ketone Levels for Ketosis, Ketogenic, Paleo and Low-Carb Diets with Easy to Read Lab Grade Results

I agree with the other reviewers before me. Adding the color chart to the strip was brilliant. It's worth the couple dollars extra but would be nice to also add it to the bottle. My prediction is having the color chart on the strip alone will far outweigh not having it on the bottle for most people.

These strips are fantastic! They are unbelievably easy to use and quick. My results show up at least within 15 seconds (I think it is a bit quicker than this) and the color gradient right on the strip makes these super easy to read and convenient. I don't have to carry the bottle around to compare the strip color - I just grab a strip, check, and move on. Super discrete. I'm loving these! Shipping was quick as expected and even the packaging looks and feels high quality. I have definitely found my favorite strip. Why even bother with anything else?

I found it incredibly convenient to have the color guide for these strips directly on the strips themselves. With these I can just pop them in a Ziploc and put them in my gym bag, no need to take a bottle with me or anything. It's also really nice how quickly the color develops.

These ketone strips are awesome! Seriously, how has no one thought to put the color chart on the test strip itself until now? That's been a game changer. I don't have to keep the bottle close to read the results anymore, so I can just take the strips with me in a small container, which is quite convenient. The test results are clear and show up very quickly (~15 seconds). For sure these are the best test strips I've ever used!

Having the keys directly on the strips instead of only on the bottle is really convenient. Very useful, works as advertised. Having been on keto for a while, trying to continually measure where I'm at with some occasional cheating takes some of the mystery and guessing out of it.

I am a newcomer to keto strips, so checked out a lot of them before settling on these. I really like the way these strips are packaged with the color chart on the strip itself. Also, super quick to use - no waiting around to see where I’m at. it's a "read, toss, and get on with your day" experience. This is sure the way to go!

So I had my friends keto breathalyzer showing me in ketosis. These strips never changed color with me. Tried over 20 times. Even once when I ate a crap ton of carbs. Same thing. No change. Don’t waste your money on these things

As a laboratory Medical Technologist, this strips are no good, they are extremely hard to read. With my 32 years of experience I can read them with my eyes close. These ones are very hard to read after it shows trace. Im ordering different ones. Dont waste your money.
