SDC Customer

The system is working great!! The interface is easy to navigate and program. Such an improvement over the keypads we replaced. When an employee leaves, all I have to do is disable their user instead of reprogram several keypads.

We purchased IP Pro systems for all three of our locations in Utah, Kentucky and Idaho. We are so impressed with the simplicity and full feature functionality that we are implementing the reports export feature to confirm attendance. We are a very satisfied customer!

I just wanted to pass along that Hunter has been a spectacular resource in making sure my customer were ordering accurate material. Also, he is currently assisting me on the logistic side of shipping the large order.

I am a fan of your company. Products are fine, but a lot more to speak about. I had an issue with poor communication by 1 of your Distributors.

Called SDC direct / Directed to Hunter. Without issue he promised to get the product I needed in our hands by a date we needed to keep. Not only was Hunter polite & obliging, he demonstrated a great attitude.

This is NOT found in similar companies anymore. Thanks for having this great asset for us.

“This chat feature was great. I was about to assume that keys weren’t available, and for whatever reason I didn’t think to pick up the phone and call, either.  Thanks”

“WooooHoooo. I LOVE SDC…. Waaaaayyyyy better customer service and closer than Schlage and I tend to get 3 week lead times from schlage”

Lucia E.

I’d like to personally thank you and the other gentlemen for your help and assistance.  It’s top-notch and you helped me greatly with a mistake that got made, believe it or not, you got competitive out there. When is a problem, it’s hard to get anybody or get a return phone call, so you guys are on it and that’s why I use [the] product, so thank you again.
