The method for calibrating these feels like a science experiment. I wanted something that just worked, and these aren’t it…The moisture and light meter is fine. In fact I use it regularly. The other 2 haven’t been used because I haven’t been through the effort to make them accurate. Wish I had known ahead of time that it was so complicated.That said, I read where you can buy the solution off the shelf to calibrate instead of messing with water and the powders that ship with it. One day I’ll do that instead of playing mad scientist.

For the proce you can't ask for much more it performs to its task and if needed can have multiple for backups. Makes it easy to use and nor worried about breakimg.

The TDS meter has been pretty solid for the last year. The pH meter has a poor battery connection so it tends to reset over and over as I adjust my grip while dipping into the buckets to check the pH. The soil moisture tester tells me everything is dry unless I just watered it so I'm not convinced that the range is very good. The built in light meter is not all that useful since it's standing up but the sensor is on the face. The pH meter always seems to tell me alkaline no matter how acidic the solution is that I add so I'm not thrilled with that accuracy either. In all I'll keep using the pH and TDS until they die, I've already stopped using the soil meter.

These meters are surprisingly accurate and worth buying for mixing your nutrients and water before adding to a hydroponic reservoir or soiled plants

Order came in a timely manner but unfortunately the ph meter came with a cracked sensor. They issued an immediate refund so I give them 5 stars. Great communication

Easy to use, not 100% accurate but maybe my other meter is off. The moisture meter has been handy for a newer grower

Update: We got everything in again finally and this time everything is working great.**********Was excited to finally get my meters and check things out, but was sad to find the PH meter was DOA.TDS worked great, but because I bought them in a set I had to return it with the bad PH meter....now we wait.I am ordering once again....fingers crossed....first bad product from Vivosun so I'm willing to give them one more try.
