They were the cheapest for my smoke… They were the cheapest for my smoke detectors . When out of stock , I received Email wanting to know if I wanted to wait or cancel . I waited , received call about 1 week later to inform me they got shipment earlier than expected . I still decide to wait , He said just text when ready for shipment . I texted when ready , and they were shipped that day . Couldn't ask for better Customer Service than this . David

Second size diffusers I've ordered from… Second size diffusers I've ordered from them, second time they exceeded my expectations. Superior in every way to the diffusers they replaced. Thicker plastic and firmer fit.

Great Find This was the first time I used Jace Supply and I am really glad I found them through some internet searching. They are very responsive to both the order and shipping processes. I will definitely use them again.

Extremely happy with my purchase of LED Lights I'm extremely happy with the LED Christmas lights I bought, The lights were the same brand as other sites but much less expensive. The lights were delivered faster than promised. I'm extremely satisfied with my purchase and will quickly do business again with JACE supply.

Quick and great service. First time customer, had the parts I needed for a great price. Excellent customer service found them in a nearer warehouse so they could arrive faster. Definetly will purchase through them again.
