    * Best way to use these is first thing in the morning. Use a small container and pee into it. Hold stick in for about 5-10 seconds, tap off excess fluid, and let stand for a minute. The readings are true for benign ketosis, but don't bother for the first 4-5 days or so. These are more accurate than the ones I previously used. Also remember to keep away from humidity/moisture (shower/steam) and keep lid very tight! A very good product!

    * Don't waste your money. These are junk. They are totally inaccurate and become inactive within a month or so after opening. I bought 3 and I'm stuck with a bunch of useless, discolored strips. Sounds like some very poor quality control or some really biased reviews. Again, DO NOT BUY THESE. Save your money for another brand.

    * Bought this and couldn't wait to try it just like anybody else. Repeatdly tried it for a couple of them, didn't work. I went out and purchase another brand, and the color finally turned.

    * These strips seem to be of terrible quality.

    I bought a package when I first started low-carbing, and they hardly ever changed color. Eventually I stopped using them and the expiration date passed.

    I bought another package due to curiosity, and the low price. Again, they hardly changed color.

    I noticed that my grocery store had Ketostix on sale at the pharmacy. These were Bayer brand. I noticed right away that the unused strip had a light tan color, whereas the LW Scientific brand was greyish.

    The Bayer brand is much more reactive and, I believe, accurate. I tested both brands simultaneously over several days. Even when I was getting a deep purple from the Bayer sticks, the LW Scientific strips remained grey. Or, there might be a hint of purple within the layers of the test paper, but not on the surface.

    * These worked just fine for me. I compared them side by side with my medical grade strips from the hospital. There was the very occasional odd duck in the pack that didn't work, but it was maybe 2 of 100 strips.

    * Very pale colors on strips compared to other brands makes these very difficult to read with any accuracy. Majority of strips were non-reactive. The Bayer brand is more reliable and trustworthy.

    * This is the first time I've ordered them here but they work fine for me. I've used them in the past. Never had a problem with this brand. Will buy again when I run out. They really help me to determine which foods my body can withstand. I like to test myself after eating something I suspect might be higher carb than the nutritional labels say for instance...low carb bagels and sugar free snacks. I've never had one fail....I'm always burning fat at different degrees :)

    * I had similar experiences to the others who posted reviews here. In a side by side comparison using the same test sample the Bayer strips worked perfectly, the LW strips were discolored right out of the package and never changed color. I was excited about the cheaper price at first but very disappointed in the results, you really do get what you pay for... and from now I'm paying a little more for the strips at my local pharmacy. I prefer to order all of my supplements and diet aids from Netrition, I really wish they'd start carrying another brand of testing strips.

    * I guess I am the odd man out but these strips work perfectly fine. I have used Bayer's and was glad when I found LW Scientific's cheaper version.

    * I have to agree with others, this product just does not work. I have tested them against other strips...these do not change color at all...while at the same time, my other strips light up like a purple Christmas tree. Don't waste your money...these will make you feel like you are doing something wrong, when you may not be!

    * These are totally useless - in fact netrition should quit carrying them. I was paying $29.00 for 100 Ketostix from Bayer and found that about 10 out of 100 were faulty (not changing color at all). I have gone through 50 of the LW strips and only 4 registered color change at all. DO NOT BUY!

    * These strips appeared to be an excellent price, but we purchased them in the summer and I don't know if they were affected by the heat in shipping or the quality is just bad. My daughter and I both tried them but they did not work (no change in color whatsoever). We had purchased two bottles and tried both bottles. We went out and bought a bottle at the local pharmacy and they worked fine. We were really disappointed at having wasted the money.

    * Awful product. The colours were off right from the start and within two months the strips stooped working completely. Don't buy this brand. Other strips work much better.
