Love these strips, have been using them since 2018. You'll see reviews of people complaining that they go bad fast and become useless. That's because they're not intelligent. They don't understand that you of course should be putting silica packets into the canister to absorb moisture and prolong the lifespan of the strips. You can buy a pack of 100 silica packets for cheap, right here on Amazon. Come on people. The jar of strips I had last purchased in November of 2024 was still as fresh as new and working perfectly right through this month, July of 2025, thanks to the silica packets. Used up my last test strip and just bought another new jar. Made sure to put new silica packets in there, and I know I'll be good to go for the rest of the year. It's common sense. These strips are highly moisture sensitive. So do everything possible to reduce moisture. If you do that, these strips will be your best friend. ;)

I’ve been using these ketone test strips for a few weeks now while following a keto diet, and they’ve been super helpful. The results are quick—usually in about 15 seconds—and the color chart is easy to read. I tested them against a blood ketone monitor and the readings were pretty consistent, which gave me confidence in the accuracy.The bottle is well-sealed and includes 150 strips, which is great value for the price. I test once or twice a day and still have plenty left. Just make sure to keep the cap tightly closed so they stay fresh.If you’re tracking ketosis or low-carb progress, these strips are a convenient and reliable option without spending a lot.

Works great, I like that each stick has a color guide. I couldn’t believe my results so I had my husband test too and results are accurate for both those in and out of ketosis

Not sure how accurate they are but they work well and easy to use.

Test strips, just right

Do not work, at all! I bought these last year and Im just now(8/20/2020) using them but the expiration date isn't until 1/31/2026. I pee'd on 6 strips and only saw a mild color change after 3 days of water fasting. Im not sure what the issue is but Im not happy with the product and can't recommend it to anyone. My guess is they are too old or were somehow damaged.

This ketone script does not work at all 🧐. I did the pee testing in the morning with no food. The pee testing in the afternoon after eating no changes. After that I was curious and stuck the test strip in all kinds of liquids and it never reacted to any thing I put it in. It looks the same as it did when it came out of the bottle. Don’t buy this crap or you’ll be sorry you did.

These strips are one of those products that can tell you really important things at very low cost. And so I cannot recommend them enough if you're on a keto diet as these are indispensable! They are very quick to respond and provide a result for the presence of ketones in your urine. Ketones tell you that you're burning fat for fuel. The fat might be your stored fat or the fat in your diet. But regardless, some people have a very hard time switching from sugar-burning to fat-burning exclusively (most of us do both automatically, but burning sugar is easier for the body), and these strips can tell you if you've made the switch. This matters very much for those looking to burn fat off their bodies, because once you've switched to fat burning, you can lower your calories while remaining in ketosis and lose weight painlessly with little hunger.This is the beauty of the low carb diets you hear about. They are satisfying while feeling very little hunger, which allows you to cut your calories to lower levels than on carb loaded diets. In case you've not noticed, sugary and carby foods *increase* hunger... but you can nip that in the bud by eating low carb, and measure your fat burning with these strips! Studies have shown that low carb diets are more effective for losing actual fat because of these reasons. Less hunger, better adherence and satiation for the duration of the diet, and with low insulin levels, better fat burning.Anyone who thinks they can't do Atkins type diets because they get tired of high protein foods, keep in mind that the goal is not high-protein, it is moderate amounts with low carbs and high fats. Fat does not make you fat without insulin. Eat plenty of greens and vegetables and the boredom issue should not exist. Also, even if you slip out of ketosis for a while, you can always go back into it. Nothing says you can't eat carbs, just dont' do it with fats or you will deposit those more readily. Food combining diets were all the rage in the 90's as it was discovered that sugar/simple carbs and fats together are what make us fat...but I digress...I highly recommend these strips for their quick and easy readings in describing your level of ketosis, critical data for those looking to burn fat the most delicious way possible!
