So far so good. Be sure to rinse well between uses or it will likely corrode.Note that any single-cell electrolysis of salt will produce bleach. You need to acidify (for example with vinegar) to get the pH down to the 3.5 to 5.5 range to maximise hypochlorous acid in the solution. Best to add the vinegar in advance, since if you add it after running the device you will create a lot of toxic chlorine gas all at once. By adding vinegar in advance, you get the same amount of chlorine gas but it is produced gradually so it's easier to vent or disperse.The recipe I'm using to generate hypochlorous acid suitable for a topical (skin surface) antiseptic is as follows: In a tall glass or jar add 200 mL of filtered water, 1/2 tsp of pickling salt (or any non-iodized salt), and 3/4 tsp of regular white vinegar (typically 5% acetic acid). Stir until the salt is completely dissolved. Use a 1A@5V adapter. Submerse the device and run it for 15 minutes, stirring occasionally. Be sure to rinse the device well after use. Then use the test strips and dilute with water if necessary to reduce strength.The acidification with vinegar is needed because, in single-cell electrolysis of aqueous NaCl, you get OH- ions also produced, and they make the resulting solution alkaline (giving hypochlorite "bleach"). If you wanted to generate hypochlorous acid directly, without addition of acid, you'd need to run dual-cell electrolysis, with a salt bridge between the two cells. Then one cell (cathode I *think*... been a while...) would contain your hypocholorous acid, the other would contain sodium hydroxide (lye) solution. You could tell which was which by a sniff test - the hypochlorous side would smell of chlorine. Or a pH test, the lye side would have the significantly higher pH.This device is only suitable for single-cell electrolysis. But it still gives usable hypochlorous acid if you acidify appropriately. It won't give you the same quality as commercial hypochlorous acid, which is (surely) produced using dual-cell electrolysis.Full 5/5 stars since they do advertise it as a sodium hypochlorite (i.e. bleach) generator, not a hypochlorous acid generator. Bonus that it *is* at least possible to get hypochlorous acid by using the additional acidification step!

What a great find, made HOCl in 30 minutes, easy, cheap, and considering I was ordering it premade and spending a lot of money, it is worth it. I put refrigerator filtered water and the salt in, used a clean mason jar, and it worked easily.

Works as intended has held up well. For the price you really can’t go wrong.Note you need your own block as it only comes with USB-USBC cord.

It works, but seems to have no timer.

Worked as intended. Didn’t come with test strips though. Wish it came with the test strips
