Brand: RSTO, Model: QBA-i, distributed by Mefe. Google these keywords to learn more about the product. Works for humans and toilet-trained cats. I bought new for $150 in Aug 2019. Excellent condition except sticky pad is less sticky, but can be easily mitigated with a 3M double sided sticky pad. Not a problem if you can mount with screws. Manual is included. Batteries are not included. Cash and pickup only.
