Great Buy!
Frequency & Longevity I bought this about a month ago to replace the original doorbell and avoid rewiring. Adjustability- Very adjustable -you can put this anywhere. I have a 6‑bedroom house and you can hear it from every room. It’s surprisingly loud for its size. Installation- Easy. I used the patch‑adhesive method and it feels surprisingly sturdy. I wasn’t expecting it to hold this well. Ease of Use-Several people have come over and immediately recognized the doorbell. I put a cover over the old wired one and everything looks clean and intentional Size Not an issue at all. The chimes fit everywhere, and there are a dizzying number of ring tones with adjustable volume. The doorbell button itself is the perfect size — not too small and not obnoxiously big. Would I Buy Again? Yes, and I already have — without hesitation.

User friendly and effective
Excellent experience! We have a multi level unit with entrances on both levels, the range of this doorbell and the dual plug in receivers has solved all of our problems of knowing when someone is at which door.

Best no hassle solution for getting a doorbell.
Works pretty well for what it is. There are tons of options for doorbell chimes available on this, the range is pretty good and has no problem with reaching the one I plugged in upstairs about 20 ft away. The door bell is small but the audio plugs will block the upper outlet if plugged into the bottom socket. Installation was easy using two wood screws. Best of all I haven't even changed the battery yet and it's been over 8 months, though it doesn't get daily use that's still pretty good in my eyes as there is no wire connection for the button.

Excellent
I’ve had the AVANTEK Wireless Doorbell for a few months now, and honestly, it’s one of those small home upgrades that makes a big difference. Setup was super simple. I didn’t need to mess with any wiring, which was a win. The range is impressive! I live in a two-story house with thick walls, and the chime still rings loud and clear no matter where I am. Speaking of chimes, there are so many options — from classic ding-dongs to fun little melodies. I settled on a calm, pleasant tone that doesn’t startle anyone. Another thing I appreciate is the volume control. You can set it loud enough to hear from the backyard. And the LED light is a thoughtful touch, especially for someone with hearing challenges or in loud environments. Honestly, for the price, this thing is reliable, easy to use, and feels like a premium little gadget. If you want a fuss-free doorbell that just works, I definitely recommend the AVANTEK.

Works amazing
I love this product! I purchased it for our office because we couldn’t hear when people were coming in and since we were new to the building, some of the old customers would just enter and walk into your office looking for who used to be there before. Since installing this doorbell, we have started to keep our doors locked, and now anyone coming to our office has to ring the doorbell. I love that you can also change the sound of the doorbell. It was definitely worth the money. It’s an easy install, and it works great.

Easy to install
I’ve had this doorbell for over 3 years. Haven’t had to change the battery. It’s very easy to install and that it has 2 receivers. I can put them in different parts of our home. You can also lower the volume and pick different ringtones.

Cuatro meses de uso y sin problemas
Ha funcionado y resistido bastante a las inclemencias del tiempo y a la limpieza que se le da debido a la pandemia. Tienen un excelente alcance ya que mi casa es de concreto y ladrillo, con muros gruesos y puertas de madera y metal, pero no he tenido problemas. El hecho de que mantienen la selección de tono aún cuando se va la luz es muy bueno ya que en la temporada de lluvia es muy común los cortes de electricidad. Lo único problemático es, debido a la cantidad de tonos, el hacer la selección se complica por los pocos botones que tiene.
