Wireless Doorbell by SadoTech – Waterproof Door Bells & Chimes Wireless Kit, 1000-ft Range,52 Door Bell Chimes, 4 Volume Levels with LED, Wireless Doorbells w/ 1 Receiver & 1 Button, Crosspoint, White

WOW ! I was very impressed with this door bell. You can choose your ringtone from 52 choices and choose your desired volume.Very reasonable price for such a good product. I am well satisfied with my purchase.

Nice product when you are in another room and can’t hear knock on door. Very easy to install.

We had an older home that had several additions. It was not possible for us to have a traditional "wired" doorbell system so the CROSSPOINT Expandable Wireless Multi-Unit Long Range Doorbell Chime Alert System was our solution. We bought the system after communicating with Sado Tech Support to understand the capacity of the system. The answered all of our questions very quickly so we bought the product... which was very reasonably priced. We are currently using the system and it works well for our front door and back door. In both situations we need to go through multiple walls, one of which is stone. I would definitely recommend this product because it is so EASY to install and provides a great solution for a reasonable price. Plus if you have questions, Sado Tech Support really does respond and get you answers!

Wired doorbell died. Couldn’t figure out the issue. This wireless doorbell is great. No issues. Cheap replacement. Highly recommended.

Has a great sound. Has different sounds with it. I bought two, one for the barbershop because I'm way in the back of the shop so my clients can reach me. Then the other one I bought for my back porch so I can't hear them if I'm outside so thanks Amazon

II live on the 2nd floor of my building. Installed the doorbell outside, on the ground floor. Plugged in the "bell" unit upstairs. Have had it for over 2 years, and it works perfectly. I haven't a negative thing to say. What a great product for so few dollars!!!! I have actually purchased 2 more as gifts!

We are in the middle of a remodel and I needed a way to get notified when the workers outside needed something from me. I got this doorbell and attached the bell near the front door with the sticky back option. This location is outside, but under the eaves, not in direct rain or wind. It has held on with no problems. The black model I got also had a small "window" under the bell where I could write a very short note ("RING BELL") to bring attention to the bell, or to identify a unit, if you need that. It was handy to have that and most of the other colors don't have it. With the black housing it helps also just to be able to put a bright color under the window to draw people's eye to the bell (in lieu of building something yourself outside the bell).The ringer has been located 1 story and about 25' deep (at the back of house) away from the plug in unit and worked fine.The inside unit can be placed anywhere there is a plug, so we have moved it around as areas of the house are decommissioned or power goes out. The volume on the ring can be adjusted to a very loud setting (if it is located near you, I found it too loud) or a quieter one.There are MANY chimes. Too many for me but there's an bell to suit any taste. It is nice to have the option of a short bell, if its where you know you'll hear it, to a longer one that gives you time to hear it if you are farther away or have competing noises. I think that's one of the best things about this--the options for different lengths of ring tones.The other great thing about this is the simple, plug and play set up. Truly, all we did was plug it in. If I wanted to change the ring tone, I'd have to read the instructions. But I hate to read instructions and didn't have to just to get it going and serve its purpose. I would recommend this and consider buying additional units if needed.

Currently in remodel mode and there's no chime to connect so this was a very inexpensive door bell. It's easy to install and the chime is very loud.
