Ordered two pop-up outlets for a kitchen island—one wouldn’t stay closed. Customer service was quick and helpful, and they’re sending a replacement. A potential hassle turned easy. I’d order from them again.

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