Great electronics, horrible spray pump
This (or a device like this) is great for having around the house, or at a remote location like a cabin or summer trailer.  All it takes is water, a teaspoon of salt, and a 2A USB source (charger/adapter) to make a small bottle of bleach mix.  No need to bring a separate bottle, store it, worry about kids or animals getting into it, etc.  Make it and use it in one go, on the fly.<br /><br />This particular unit does the electrolysis need to make the bleach without an issue.  The problem is in the nozzle for spraying.  It's designed to have a pressure system that allows you to squeeze the trigger multiple times and the unit sprays the bleachy water in a fine mist continuously.  Sounds great right?  Except the nozzle gets clogged within minutes, and a safety valve starts rediverting the stream back into the bottle.<br /><br />Why would this happen? Because you're literally converting table salt into bleach in an imperfect system.  If even a small clump of sodium remains (which is highly likely) it can and will easily make its way to the nozzle and clog it.  And how do you unblock a pressurized system, filled with bleach water?  Carefully, wearing clothes you don't care about getting bleach on.<br /><br />I bought this mainly to make bleach with.  I plan to 3D print a small cap for this, and simply use it to make the bleach I need, then pour it into a proper dollar store spray bottle and use it on demand.  While it would have been great to be able to use the sprayer directly from the bottle, it's not worth returning, given the price of the unit.  You could also use a pin to enlarge the hole, but then getting the aim right is kind of a pain.<br /><br />If you're looking for one that works as a spray bottle as well, pick another design.  This one sucks.  If you just want it for making bleach cheaply? Grab it, and look for a cap for it over on thingiverse, where it will eventually be posted. :)
