Not that accurate

very fast shipping, accuracy with product, always available great value easy to use readability available highly recommend seller

I’m giving the test strips one star because they work. However, if you’re buying Aquacheck for the app camera capture to use a test strip and use camera to tell you what to do (like I was), forget it. The app does not work. Apparently they made changes to the app and it does not work anymore. Literally 15+ tries to auto capture the strip and not one try worked. Read the recent online app reviews and they will tell you the same thing. Skip these and get another brand of strips if you want an app with camera capture and guided instructions. Until the app manufacturer fixes this app, I can NOT recommend these strips unless you want a purely manual test experience. The in app camera experience will not take an in-focus picture that works AND the mere challenge of aligning the top square and bottom square perfectly to take the “ideal” photo is just not possible. Skip the pain, extra money and look elsewhere.

perfect

I like strips for their ease of use, and I really like these because they measure CYA/Conditioner. I have been impressed with the accuracy, though they are not as on-point as liquid reagents. In general, though, they are "close enough," and they certainly are fast.I have used the app only a couple times. It works remarkably well, though it takes a while sometimes to get a good photo of the strip and I really haven't yet figured out why it sometimes works and sometimes does not. When. it does work, it's kind of cool. I'll be trying to perfect the technique.I've seen comparisons with much more expensive kits, and while the other kits are more accurate as far as knowing the exact level of various thing measured, these proved to be consistent and as accurate as the range can be. In my use they are very consistent and the items that duplicate my other test kit (total chlorine, free chlorine, PH, etc.) are almost spot on -- again within the relatively wide range each color splotch represents -- with that kit. The chart is easy to read.
