Accurate and reliable
Comes with everything you need for continual and accurate PH readings. Way better than the cheap options I took first (my mistake!). I recalibrate using the solution supplied around every 4-6 weeks. Great we unit and comes in a quality case to keep everything together and protected.

Not accurate
Not accurate. Along with some bad reviews I seen but over powered with good, I had doubts spending this money.The inconvenience in returning has thought me the value of buying valuable items from a shop. Will avoid amazon on expensive purchases in future.Freshly calibrated and spot on at 7.At 5.8 it's off by 0.2-0.3 reading 6-6.1. Expected from a cheap €10 meter not a 75 one.

Working again
As with many people here, mine worked well for a while and then stopped calibrating. Customer service required me to post it to Germany at my cost to see of it was damaged or if it was faulty. I left it in cleaning solution for several days and it still wouldn't work, but then gave up on it and after several weeks of being in cleaning solution I tried it again and it was working fine. It's obviously a flaw of this model, but it is a well made item otherwise and if you keep it sitting in cleaner then you will probably be fine.
