My go to device when measuring the effectiveness of our under sink reverse osmosis system. It shows that even when new - store bought distilled water registers 0.0 (the purest possible) while my RO system comes close but never to the point of 0.0 (0.1 was a one time best, normally 0.6 ppm). This may be unimportant top most people as far as drinking water but for medical devices requiring expensive distilled water it makes all the difference in revealing what is and isn't suitable.

We only got to use this one time and then it somehow got lost from our bag :(  From the one time we used it appeared to be working well.

I only had to use it one time but it worked as advertised. Everyone that sees it wants to know where to get one. One use pays for it.

Inexpensive and easy to pack but they only worked once.  Second use and the splitter only delivered sound to one set of headphones.  Lesson learned - don't go for the least expensive option.

It worked only one time.  I needed it again 45 days after purchase and it won't work on any of my 3 pc's.

I worked well the first time, but when I wanted to use it a few days later, the liquid had hardened inside the nozzle.
So, great for a one time use, but I need to try to unclog the nozzle to use it again. I hope it doesn't clog every time....

The "Best Before:" date on this product was less than one month after my purchase date.

this worked great 1 time, then during the second use 4 months later, the fan quit working.  This let the temp next to the eggs drop way too low and ruined the hatch.  I expect an item to work more than 1 time.

I was able to change the combination one time and after that the keys would not move to reset it again.

I would like it more if it worked consistently. I would say it works 1 out of 10 tries.
