I have had one about a year and have replaced the batteries before successfully. Now the batteries died and with the replacement batteries (which are good), it still doesn't work. The black button is working

Sorry, mine didn't even work. I think we got taken. Maybe Amazon will remove them from their site.

I have two of them that I bought over a year ago and they have worked flawlessly. My experience has been great. Hope you have better luck with your next one.

I've had to replace mine in the past. Sometimes they just stop working. If it was within 1year of your purchase, they should send you a replacement at no charge.

I would ask them for a replacement. Obviouslt a problem with the battery. i have found they are either great or duds.

Make sure you change both batteries at the same time. Do the one on the door first. Also I had one that quit working and the company sent me a new one in just a couple of days. Have not had trouble since. Really good customer service. It does have a warranty.

Mine were the same, tried new batteries, that didn't work so I sent them back. Too costly and I got frustrated with them. I really liked them when they worked!

So far mine is working fine. Had to change batteries after about a year, but that is expected.

If it is a new unit, try a different new battery (as the battery could be defective), followed by a different new unit.If it is an old unit, I would suspect it has failed (i.e. reached its lifetime, say over 5 years), and needs replacement.

mine has worked fine for over a year now. HOwever, I purchased one for my son with the same model number and it looks and acts totally different. this unit is 6 months old. It also came with one dead battery. Appears the service charge to resend the unit and or battery was not worth the money so we are dealing with my 2 that work and his one.

It's special low power circuitry keeps drain to a minimum. Before each use, check power with the test button. If the light does not come on, replace the AAA batteries. Had mine since April 2013 and batteries are still good.

I've had mine for several years and it works perfectly. You should get it replaced.

I haven't replaced them yet, but I haven't used it much either. I did have problems getting it to work when I first put batteries in it.

I have two like this, but they're a little different from each other. I remember once I thought one of them was broken because I had just changed the batteries but it would not turn on. Then I realized it wasn't set to play on batteries or something... I can't remember exactly what the issue was, but it was a very "duh!" moment. Otherwise just get another one - it's $6 crap from China.

You are lucky. Mine didn't last long enough to need new batteries. It was a complete waste of money. Sorry I couldn't help.

I have mine for over a year now, and I just have to replace batteries after awhile. The unit even has a indicator for battery replacement, so you don't need to guess. It is still working, and I've zapped a giant rat the other day. Disgusting, but glad that thing is dead.

I've had mine for almost a year and it works fine. But I didn't realize it needed batteries till I got it. Not sure if this helps at all, but I hope it starts working.

I have not replaced and have had for a few months. That is why we replaced the one we had before (not this kind) it ate batteries every few day. Have not had problem with this one at all. Very pleased with this mouse!!
