Before I buy this, I wonder if it can be refilled with any kind of hand soap or do you have to buy their refills? I couldn't tell by looking at the box. The concept is neat but I can get softsoap so cheap and would like to refill with that. Anyone know? TIA

I actually got to try this out over a year ago. I was chosen as a tester. I really loved it. I think you may have to buy their refills, but I am not sure!

I bought one a few weeks ago. I like it, but my boys complained about it going off easy. I think it dispenses too much soap and you have to make sure you keep your hand under it till it is finished dispensing.
You're supposed to buy the refills, I was able to get the cap off & refill it.
I switched mine to my kitchen for dish soap.
HTH,

If you google "automatic soap dispensers" you'll find a lot. I got this one several years ago:
Automatic Soap Dispenser : Target
it runs on batteries and can be refilled with any soap.
