M520X2+F55 Wireless doorbell

Husband installed in minutes. Doorbells work well with many different options for ring tones. The sound quality is good. If you need 2 doorbells with 2 receivers, we totally recommend you buy these. Good product at a good price.

The Secrui Wireless Doorbell - Model M520+F55 - that was advertised attracted our attention primarily due to the simplicity of installing it without the need to call in tech support as well as the very high ratings received from users to guide us. Combining both quality and affordability was indeed an attractive option. After nearly three years of flawless operation, an occasional false alarm was noted. Even though the warranty period of one year had long expired, I tried to troubleshoot my way through Amazon.com, but without success. Thereupon, I turned for help direct from the manufacturer in China (PRC) using an Email link for customer support. I was astounded by the rapidity of their response – less than a day. They were very sympathetic and their response outlined a series of steps to fix the problem. Although I attempted to follow the guidance, unfortunately my unfamiliarity with the working of electronic devices stymied success. I confessed to Secrui as much, but not before conveying my profound thanks for their efforts to set my mind at rest. But Lo and behold, literally within a FEW HOURS, I received a message, and I quote “we are very sorry your problem still exists. I am happy to apply for warranty and replacement for your order.” Words failed me at this magnanimous gesture. I was overwhelmed with this generous offer of a full replacement long after the expiry of the original warranty. I have not experienced such an enduring commitment by a highly reputed multinational company with millions of customers to listen to and act on the submissions of a single customer. This is an extraordinary event of lasting memory, The awesome speed of Secrui’s attention to the issue flowed through to ensure that within two days the full replacement of the device reached me at home. The instructions for installation were very clear and easy to apply. It is working perfectly.

These doorbells have been such a helpful tool in my classroom. The sound is clear and carries well without being too loud or distracting. I like that there are multiple chime options, so I can choose tones that fit different activities. The setup was quick and easy, and the remotes are very responsive. My students immediately understood the cues and it has made transitions and classroom management so much smoother. The battery life has been great and the range works perfectly even from across the room. This has been one of the most effective and affordable tools I have added to my classroom.

Bought for my disable Dad, with the push of a button, he can be heard all around their house. Serves the purpose great. The range is surprisingly large. I put one receiver in the garage, not expecting it to reach but wanted to try, surprisingly it did reach. Easy to set up. Just plug the receivers in an outlet. The push button can be adhered to a wall or anything. For our purpose, we leave the remotes near him. Great value, money well spent.

Awesome! Worked 10x better than expected. Read instructions took 5 min. Setup took 2 min! Wonderful, simple, value-add product! HUGE FAN!!

Very easy to set up.

Love the price, love that it’s loud and very durable.

Easy to install and works as expected. Has many ring tone options.
