How does one know when this product stops working?

This product doesn't eliminate scale, so as long as you can remove it from plumbing fixtures with your fingernail, the descaler is working. I've had mine for a year and a half, and it still works perfectly.

It does not start working. Please not the claims the seller made violate the laws of physics.

With this kind of a product one has to determine whether it is functioning properly before asking the question about it having stopped working. As I understand the initial function of this product is to electrically charge the water or calcium so the calcium will remain in solution. One way to make a determination is to let a small amount of water drip on a sink or tub, let the water dry and if the sink or tub does not have a white buildup, then the unit is working. When calcium is held in solution with the water, there will be no calcium buildups around faucets or other places where water is allowed to collect and evaporate. If the unit is working properly you should notice an increase in soap suds and the water will feel softer on one's skin during a shower. I hope these remarks will be of help. Dwight H.

First, the red and yellow lights would not be lit on the unit. Second, You would begin to accumulate calcium on your appliances. Be sure the unit is firmly attached to a wall or other unit. If it falls the one of the yellow or red cords m or the power cord may become disconnected. My unit has been installed for about 10 months.

Mine has stopped working from time to time... I've disconnected it, then re-connected it, then re-booted the machine, then it will start working. As stated earlier, make sure that it is properly seated. It should be plug and play, (I don't believe it's Bluetooth, like the keyboard I bought for my iPad). Seems to stop working, at times, when the machine goes into "Sleep" mode. If this doesn't work for you, I would suggest contacting Lenovo, under the assumption the products are still under warranty they should assist you, or worst case, replace it if found to be defective. Hope this helps you?? Mine has stopped working from time to time... I've disconnected it, then re-connected it, then re-booted the machine, then it will start working.

Unfortunately, you'll never find out, as the product does not work from the start.

Check it by plugging it to a cord and light and put it in a freezer (light out of freezer) and wait a few minutes

I really don't know because mine does the same thing. It's really pretty bad product. Mine is not working at all now.

My best guess is to contact customer service. Because mine still works very well.

As long it works perfectly, I can't offer any advice if there a problem with it. Enjoy using it.

I suggest that you not purchase this item. If you get one that works, it is fantastic, until it stops working. It is not worth the headache of costomer service to fix/replace.

Yes, that's right. Mine worked nicely when I first got it...then it stopped working.

I've had this diffuser for over a year and this happened to me as well where it stopped working. I unplugged it and rinsed the inside with warm water and left it to dry for a few days. When I plugged it back in it worked and has worked ever since. Sometimes it will turn off and on and I will repeat.

I'm not sure why it died. I've used it almost everyday but never faced any issue. May be u got a faulty item. If u want anything else let me know.

I bought mine 4 months ago. It still works so far. I'll let you know when it dies.

Presumably so when the first one stops working there is another one available. Unfortunately just after I submitted my earlier review, the first one DID stop working. The second one worked once. I've taken it apart and neither I nor my husband can determine why is has failed. Too bad because it was great while it worked.

To tell you the truth, mine stopped working, hopefully I can repair it myself..so you might want to get something else

I am very sorry to say I do not know how long the warranty is. I only know when I tried to contact them I did not get a response. I thought registering the product would help, but since no one responded to my e-mails it didn't help me. I really liked it when it was working.

Mine stopped working, but not that fast. I got about 3 months' use out of it first.

I don't believe there is a way to tell until the transmitter and/or receivers stop working. The batteries should last a long time though. We have devices that use the same battery and they lasted at least two years, in most cases more than that long. Hope this helps.
