Does it need batteries?

No batteries. It's just a mat with several very sharp plastic pointed spikes which after laying on it give you lots of relief.

No, it's battery operated and I have to say I wish it did. The lights are very dim and the batteries burn out quite quickly.

No. This thermostat does not use batteries. This is a primary reason for my purchase.

If I remember it does not require batteries. To make sure, either call Amazon or inquire through their Customer Service. I gave this to my grandson last year and I am pretty sure it did not require batteries.

It came ready to use. It did not require batteries. Whether there is an existing battery that may run out at some point, that I am not sure about. All I know is that it did not require batteries right out of the box. It has provided hours of music and if pun for our granddaughter.

Yes it does, and mine takes batteries as well, although I have never tried using batteries in it.

It doesn't need batteries. Mine too inexplicably stopped working after a short while. I had to return it.

If it doesn't have an electrical plug attached - then no. I bought two: 1 uses electricity and the other uses batteries.

Yes mine does but the batteries last a really long time so you may not need it.

No. It does not require batteries. It uses the 24 volt power from the HVAC unit.

Not at all. Leave the batteries in in case you need them. Plug it in when you can.

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.

No batteries needed. This is a handheld /supported by the cord that goes around your neck. It is a rather light weight clear plastic. Any light would come from a lamp or daylight. I can see that it looks like it might be lit in the photo.

The product I have does not require any batteries, maybe if there is one to purchase with a 'light' added it may need batteries, however the stand alone needs none!

No, it does not come with batteries. I wish that it had a rechargable battery instead. Costly. :\

It does require batteries. I think they were AA. That's all I have in the houses and don't remember having to buy them.
