All good I was replacing a whole large duplex of wired smoke alarms and the replacement needed adapters as well. Got everything I need here just fine at a competitive price. The contact was knowledgeable and I got a personal response, which was great during a pandemic. I'd definitely use Jace Supply again.

Just what we needed JACE Supply had just what we needed to replace our aging fire/smoke alarms with the least amount of effort and at the best price. The customer service was excellent as they kept me updated on my order and didn't mind me asking questions 😁! I would definitely recommend this company!

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.

Quick response to orders and questions Quick response to orders and questions, excellent customer service, fast shipping. Just a great company all around in the days when pre or post purchase support and service is unheard of. David M. Visconte

I highly recommend Jace Supply I highly recommend Jace Supply. I ordered a large quantity of smoke detectors. Their communication was excellent as they notified me the items were back ordered. They arrived in a reasonable amount of time and were well packaged.
