SanJie Door Chime, Door Open Contact Sensor Alarm for Business/Store/Home/Office When Entering, with 500 FT Range,26 Chimes 5 Adjustable Volume 2 Receivers +2 Sensors

They are great, I paired them to existing monitors and it was a breeze. The volume is easy to adjust and using different sounds for the different places was also easy to do.

Bought this on May 11, 2021 for our office. Posting this review on 9/29/21. It has worked well for the entire time. Just today the batter on the device that goes on the door died. It takes a 12V battery. Got that changed and bell along with sensor is working just fine again. At the highest volume, the base receiver can get really loud. Our office is not that big so we keep it on a lower volume. We have it placed on a door that opens out, there is a porch area type right outside the door, so I am not sure how it would hold up if it was completely exposed to the elements. However, when I pulled the door sensor to change the battery, the 3M sticky foam did not budge. I was able to unsnap the top to change the battery and the 3M sponge/foam stayed with the base. So far, this was a great purchase for the price. Not to mention that comes with 2 sets.

I like how easy they were to operate and set up. I like the set, they're nice they work, and they easily hold on the door. The one thing I don't like at all. The alarm goes off when door first opens and also when it closes.. but the door alarm will not keep sounding if the door is left open. Although the door bell knows the door is not closed but it still stops doing off... but other than that I love them... they was around $25 to $30... not expensive at all!!!

I Run my own store and it's a pretty big company and I use this on our doors so my team and I can greet every customer that walks into our door. It worked perfectly for what I needed. My favorite feature is the volume control . If I'm working alone I can turn it up so I can hear it at the back of my store. The sensors are amazing as well they catch every person that walks in. I'm amazed. So glad I chose this company!

I purchased this having no issues with the previous version (except the battery change every few days)..worked really great at first. A month into it one of the receivers just flashed, no sound. No biggie as I had a second one. That one has quit working as well...they are 3 months old. Of you use this for business and enjoy being caught by surprise by customers...by all means get it. Would really appreciate a replacement as when they do work, they work well.

Use these for my shop. We are in the back more than not so we needed something to alert us when a customer arrived. These were perfect. You can change the chime and the volume. Very easy to install!

Easy to install I love it, has different sounds but for some reason stops ringing when is just been installed

Bought this to alert my mom when someone opens her back door. It was so easy to install, works well. Only down side is that both parts are stuck on with adhesive rather than having a screw in option, so you may experience them dropping off if you place the unit in 'high touch' areas of your door frame. Still a great device for the proce!
