Incredible after sale service.

i got a package problem and the crew never let me down. Took charge of the problem and 2 days after everything was resolve.
Thank you

I wish I could give 10 stars but the max here is 5 stars.

I searched so many stores and many more and they all had the Siemens breakers that I needed out of stock and priced sky high but luckily for me I found this company, who not only had the breakers in stock, they had the lowest price for crying out loud. I received 4 breakers on the second day of placing the order and it seemed like Siemens shipped it directly as the quality was mint and outstanding, beating all the big box stores out of the box. I highly recommend as they helped me when no other store could. 10 stars


Best prices, fast delivery, and great customer service.
