I recently installed the SECRUI Door Chime at the office, and it’s been great. The installation was super easy—no tools required, and the sensor synced perfectly with the chime. The 400ft range is impressive too; I can hear it clearly from anywhere in the house, which is perfect for larger spaces. I also love that the volume is adjustable. I can set it loud enough to hear in busy rooms, but not so loud that it startles anyone. The chime sounds are pleasant and not overly annoying, unlike some cheaper models I’ve tried before. Overall, this door chime makes it easy to know when someone’s at the door, without any hassle or complicated setup. Highly recommend for anyone looking for a simple, reliable door chime system!

Great value for the money for sure!!! My son is 4 and he's autistic. He loves to open door and try to go outside alone. These alert me from the front of the house to the back! I have them on all doors that lead to the outside. They work well. They have an adjustable volume, as soon as the door starts to open they go off! Best Buy!!!

I absolutely love this door chime. I care for my elderly parent who has Alzheimer’s and advanced Dementia, and I needed a reliable way to stay aware when she opens any door without frightening her with a harsh/agressive alarm. This chime has been the perfect solution, and the functionality has been completely dependable from day one. Instead of using a traditional door alarm, I chose this chime because I can place the plug-in receiver in whatever room I’m working in and adjust the volume to a level that alerts me but doesn’t upset her. There are multiple tones to choose from, including gentler options that blend into the environment while still getting my attention immediately. The responsiveness has been excellent every time a door opens, the receiver chimes right away. Another huge benefit is that it doesn’t cause unnecessary noise every time I let my dogs out, which happens several times a day. With the ability to select the tone and volume, the household stays peaceful while I stay fully aware of every door event. Mounting the sensor is simple and flexible. The listing includes both peel-and-stick adhesive for quick installation and screws for anyone who wants a more permanent, secure mounting. I’ve used the adhesive on most doors and it has held well, but I appreciate having the screw option for areas with heavier use. Setup was extremely easy, and I appreciated that no pairing was required. It’s basically plug-and-play: decide the best placement for the sensors, mount the sensor, plug in the receiver, and select your tone and volume. It was ready to use in minutes. Functionality extends beyond caregiving, too. While my primary goal is monitoring my parent’s movements, this chime also adds an extra layer of safety and security. It gives me peace of mind knowing I will be alerted whenever a door is opened; whether during the day or, more importantly, at night when the household is asleep. Additionally, you could use this on windows, cupboards, refrigerator, etc. I can’t speak to longevity yet, but it uses a replaceable battery (AA or AAA), so I expect at least several months of use before needing a new battery. Even 3–6 months is absolutely worth it for the peace of mind and reliability it has been providing. It works flawlessly on my front, back, and basement doors. Overall, the functionality, ease of use, and simple design make this one of the most helpful items I’ve purchased as a caregiver. Highly recommended for anyone who needs dependable door alerts without causing stress or noise AND who wants added home security as a bonus. I definitely will be getting more!

Update: I figured out how to take it off the door to change the battery, and now it works again. One star removed because I feel like it should last longer/be easier to change the battery. Also, after I left my original review, the company reached out to help with instructions and offered me a refund. --- Original update: It worked fine and was easy to install initially. But 6 months later and it just stopped working. It looks like the door sensor and the receiver are no longer paired? Or maybe the battery in the door sensor died? But because it's attached with double sided tape.. not easy to remove and try to fix.

Works well, be careful when you change the battery; the mechanism fell out of mine when I removed the transmitter to change the battery. Lasted exactly 1.5 years and now doesn't work. In the market for a new chime that lasts longer.
