I placed an order with Sonic Electric and after receiving needed to return the items. I was so pleased to get prompt personalized attention and a full refund. So nice to do business with a customer oriented company.

I recently ordered two pop-up outlets for a kitchen island. One of them won't stay closed. I emailed customer service, and after a couple of email exchanges and a photo, they are shipping a replacement. Things like this can be an absolute hassle, but they were great. I would not hesitate to order from them again.
