Everything works except for the three-in-one soil moisture light and pH tester the moisture seems to work and the light meter may work I can't disprove it because it's in lux instead of ppfd but the pH tester does not work it always says 7 to 8 even when I mixed a 4.0 solution

Talk about a good deal. I tried the TDS and EC meter and they appear to be working well. I did not have a stable solution that I could test or calibrate it with, but they seemed to perform well. The green soil tester was a bit unreliable thought. I was hoping to be able to monitor the soil in my garden, but the meter never seemed to move at all on the PH scale. I tried waterlogging the soil and only then did I get any movement but not much. I know my soil is on the acidic side because I did some soil tests through the local extension and they did not match with this meter. Either this meter isn't reliable or the extension is doing something wrong. I'll leave it to you to decide. Maybe it's just user error, but unfortunately that included instructions wouldn't be able to help me there as they are very vague and sparse.

What do I like about this kit? NOTHING. To begin with, they aren't waterproof. What kind of idiot designs a product that is to be immersed in liquids, but doesn't make it waterproof? There isn't even a line on the devices to illustrate where the sensitive electronics begin. That information is pointed out on a slip of paper included with the device. It wouldn't cost the company more then 5 cents per unit to use silicone to waterproof them, so it's just a case of cutting corners for maximum profit. But that wouldn't be the end of the world. Sure, it's a dumb decision, but it isn't necessarily a deal breaker. And you could replace these every month for two years before you hit the amount of money that you would spend on a laboratory grade pH tester. So, there is that. The major problem is that it simply isn't accurate. The pH tester seems to calibrate just fine, but every time that I test the same sample, I end up with a different number. It's the same sample, how can the numbers change every time I dip the sensor in the water? And I don't mean, "It was 5.7, and now it's 5.9." I mean, "It was 5.7, and now it's 4.8, no, now it's 6.2, wait it's 5.3" ***sigh*** Then there is the device settings itself. The backlight shuts off after two minutes, but it takes up to 5 minutes to get an "accurate" reading according to the manual. The dark gark grey text on a light grey background isn't super easy to read after the light turns off. Pushing the power button will turn the light back on. Or maybe it will turn the device off. The R-N-G Gods will determine that for you. The device has a 5 minute auto-shutdown that can't be disabled. What kind of idiot designs a device that shuts off at the EXACT MOMENT it is supposed to achieve an "accurate" reading? And, then, when you restart the process you get a different result. This is the only Vivosun product that I own. It will be the only Vivosun product that I EVER own. You get what you pay for. And what Vivosun has taught me with this device, is that Vivosun provides cheap trash to unsuspecting customers. I'll be purchasing a proper waterproof, lab grade pH tester. If I'm gonna get high quality hydro grows, it only makes sense to invest in decent equipment.

the meters are great . only issues is constant calibration of the ph water meter . which if you want good reading calibration is important but this one seems to need a little extra calibrating . other than that i get good consisent readings from all tbe devices the tds meter and the soil multi meter .
