I use it in the shop and it works great. We probably have a bell about 125 feet from the front door with no issues. Exactly what we need for our business to hear our customers. There's nothing quite like being surprised when a customer you've never heard of shows up for a wake-up call. Speaking of alarms, if you are installing one in an alarm shop make sure you install it far enough away from the alarm door contact or in the correct order to not set off a false alarm as the magnet that comes with this bell is extremely strong.
