Review on 🔌 Hanna Instruments HI73127 Polypropylene Connector by Christopher Wiggins

I only had to buy these because the HI98128, which I also bought from Revain, arrived dry and defective. And when I did something, it was too late to return the device. So I ordered this and it came to me dry too, but at least it works after leaving it in a storage solution overnight. It is shortly after you receive it, so you can return it if you need. You can also buy a spare tool if you want, but removing a dead electrode is pretty easy with a good set of pliers, especially since you don't have to worry about damaging them since you can't hold them. Inserting a new electrode is fairly easy without pliers. I just did it with my hands and a ruler to screw it down.
