great doorbell!
This little Avantek wireless doorbell is exactly what I needed! Our old doorbell was on its last leg, and I didn't want to deal with the hassle and expense of rewiring. This one was super easy to install – literally just plugged the receiver into an outlet and stuck the button to my doorframe with the included adhesive. Took maybe five minutes, tops. I was a little worried about the range, as my house is fairly large, but the signal has been surprisingly strong. The button is on the opposite side of the house from where I plugged in the receiver, and it works perfectly. No missed deliveries or visitors anymore! The chime itself is nice and loud, but not obnoxious. There are also a ton of different chimes to choose from – I think I counted over 50! It was actually kind of fun going through them and picking one we liked. We settled on a classic "ding-dong," but it's nice to have options. The fact that it's waterproof is a big plus too. We've had some pretty heavy rain lately, and the button hasn't missed a beat. No worries about it getting damaged by the weather. For the price, this doorbell is an absolute steal. It's simple, it works, and it was incredibly easy to install. If you need a new doorbell, I highly recommend the Avantek Wireless Doorbell. It's a great little gadget that does exactly what it's supposed to do.

Awesome Doorbell
Excellent door bell and super easy to install. Simply plugin the receiver, then stick the button next to your front door and you are good to go! The receiver (actual door bell) is very loud and has a ton of different sounds that it can play and can be adjusted to the volume and sound you want. For the price, you just can't get any better for a door bell. I have bought 4-5 now for various houses and have never had any issues. Also the actual door bell button sticks very firmly by your door - I have never had one fall off yet over 4-5 years.

Loud enough to hear, but only like three tones that aren't super annoying.
This works great. I got it because when I'm in my home office, I can't hear people knocking on my front door. It's plenty loud enough with the receiver in my hallway. It has something like 53 different options for the ring tone, but most of them are weird animal noises or jaunty little tunes played through a tinny speaker. Still, it paired easily, mounted easily, and you can change the tone and volume easily. I snagged this one on sale, and it was a great value for the price I paid.

Easy and Effective
Have had this doorbell since 2022. Absolutely ZERO problems. Very highly recommend!! Simply place the button wherever you want it outside and plug the device inside. Done. It's that easy. You can change the chime and volume. No regrets.

Dependable and easy to use.
Works great now when someone is ringing the doorbell we can hear the doorbell ringing. I like that it was easy to set up. The only thing I would recommend is putting 2 strips of double sided tape in the package. The one that was in the package only one side was sticky.

An Effective Medic Alert Alternative
After two mini-strokes left my balance occasionally shaky and an outside fall, I went looking for a convenient device that would let me signal my distress to an audible alarm. Most of the available device seemed to of questionable quality and limited range and cost $30-$50+. So I thought of a wireless doorbell. This one cost less than $20 and the transmitter was weatherproof while promising excellent range. It has delivered perfectly on all counts. The range has been tested at over 200' through multiple walls. The transmitter is small with a large button. The unobtrusive receiver plugs directly into a wall outlet and is quite loud. It offers 52(!) ringtone choices, perhaps a bit silly, but whatever. I'll get a neck lanyard, making it perfect for my needs. A five-star solution!

Great thing to have!
We live in a basement without doorbell so we figured we'd try one of those and we are pleasantly surprised! Easy to install, easy to adjust and nice design! We love it

Buen artículo.
El timbre se siente de buena calidad, el sonido no es tan molesto, en comparación con algunos timbres baratos que podemos encontrar por ahí su color es en negro y es muy estético. Llego en tan solo 3 dias.
