Not a 100% reliable seller/make
In 2024 I bought 3 probes for my reef tank, previously I had bought 2 probes (same make) about 2 years ago (that worked just fine):- one of the probes had signs of scractes on the body, which I kind of ignored... how naive was I - the probe drifted 0.3 PH points within a 2 week time!- other 2 probes are OK..From what I can conclude - if someone returns the probe because it's faulty, the seller just repackages and ships it on to the next customer. Not going to buy Extech again and definitely not from this shop - would rather pay for a proper Milwaukee double junction probe.
