My tabletop fountain, which I've had for years and has great sentimental value, does not have an on/off switch. The last time I pulled it out of the wall socket, the safety prong came loose and remained in the wall socket. I e-mailed Homedics about this on Wednesday, January 2, 2019, and received no response. I called twice, left messages, and never received a return call. I let it drop after I questioned a couple electricians, both of whom told me to not re-insert the prong, and it would be too expensive to replace the plug or cord. On Monday, September 16, 2019, I tried Homedics again and this time someone answered. I was told that it was an old model (I already knew that) and they basically couldn't help me. Before hanging up, the CSR asked someone about an 'adaptor' plug, but turns out they didn't have one. After thinking about it, I decided all it needed was another plug that did have a safety prong. I found one in my toolbox, plugged it in and...guess what? IT WORKS. I am extremely disappointed in Homedics for not telling me to just go get a stupid adaptor (I'm not an electrician; I really didn't know). Naturally, they wanted me to buy a new one. However, I don't need one now, and I will NEVER buy a Homedics product again. I have other products of theirs, and they never last long.
