Work Great. Seem to be very accurate.
These work great. I can see they work correctly because it showed high Ketosis then I had a cheat meal and it's back to showing me out of Ketosis. Then I watch Ketosis slowly start again as I am strict with my carnivore diet and they're fully registering Ketosis around the 4th day. One day I had been super strict with absolutely zero carbs for a few days and felt like death. I said I am probably in the highest Ketosis judging by my eating and how I felt. I did the test and sure enough its really dark red meaning super high Ketosis. I just said "Yep, that's why I feel like I'm dying" (attached that photo). So they are consistent with how I eat and feel, so I know they are accurate and I am losing weight quickly. One cheat meal and it knocks me out of Ketosis as expected. It helps me not to cheat, because I see by the tests that I take 4 days to fully enter ketosis again. No cheat carb is worth the 4 days to re-enter ketosis. The only drawback is once you open it they only last about a month, so take as many tests as you want, because they will expire quickly.

Good product and price
The keto test strips have had no problems. The longer stick is nice, though it is 40 seconds to wait for the results, it is a good product.

Not reliable at all
I purchased these as a cheaper alternative to another brand I have from my doctor. I tested them thoroughly and discovered they were not reliable at all. My bottle stated the expiration was not until 2027. First test: While late into fasting, I compared these strips with those I received from my doctor. These showed no indication of ketones. Second Test: I repeated the first test at a later time. Same failed result! Third Test: I used 4 of these strips on the same urine. Two had no indication. The other two had inconsistent color change. The purpose of buying this product is to reliably detect ketones. This product cannot be relied upon to meet its intended purpose. I would not recommend this product to anyone. They have no value.

Very Limited Benefit, Results are Inconsistent, for Keto Dieters: Consider Blood Testing Instead
So in general urine test strips are not highly accurate for assessing mild to moderate ketosis. You can get a zero or 0.5 reading even when it should be much higher. If you do not know this, these test strips might confuse you. The results for me have been very inconsistent, and as someone trying to adjust my diet and react to what might be taking me out of ketosis. These test strips just do not provide me with results I can be confident in. The two test areas on each strip commonly read differently, the inner one seeming to react more and darken in color. The colors are difficult to distinguish from one another. I found that squinting and blurring my vision helps, while holding the strip up to the bottle to identify which band I match. I'll say this: If you get a 4.0 or higher using these test strips, you are certainly in ketosis. Anything less, you may or may not be in ketosis. If you are serious about the ketogenic diet, go ahead and spend more money for blood testing strips and a reader. These may confuse you more than they help you.

They're worth it!
Very cheap and very accurate. I measured them against my ketone meter and they work very well and have proven to be accurate. Just keep them in a cool dry and dark location. If you leave them in the sun it will ruin them.
