I just purchased this wireless door bell from [url=https://www.adoriclife.com/index.html]Adoric[/url] and an extender (a 2nd ringer) in hopes of having an easy installation, and a range of 150' (or so the packing promised) .. I have come to understand, this is not the case. Although the installation was easy enough, and both ringers work they are plugged in within 15' but .. no farther. What's the point in having an extender that provides no 'extention' of the ringer? Anything more than about 20' then it's out of range. Has anyone had an experience with this product?

Do you have a model number of the items? We maybe able to look it up ad see what can be found.

I have had years of experience with these devices. In general, 150' is just about the maximum (with a little bit of luck) in the open field. Once the devices are brought inside all bets are off. Reflections off metallic objects, e.g. a fridge, a mirror, metal door, can reduce the usable range to just a few feet. You can usually achieve an acceptable operation by trial and error by moving these devices around.
These devices usually operate in the 300MHz range with the 1/4 wavelength approximately one foot. The signal through the house, because of the reflections, is usually distributed in peaks and valleys. Moving one device about a foot in some direction can often bring the signal up from dead.
The above doesn't apply the same way to the modern breed of wireless communications devices such as those used for the IoT! However, products like doorbells are likely to be still using the cheap old technology.
Good luck.

I never said the range or the signal propagation characteristics bothered me. I merely stated the facts based on education and years of experience.

150' is the open air rating.
As Geo pointed out. You may not get 150' if anything is between the two units

Signals are Reflected by metallic objects, e.g. a fridge, metal windows etc, and can reduce the usable range to just a few feet.Chek if some thing like that is between move it from tha place.

Culprit surfaces don't necessarily have to be in the line of sight. Quite often you deal with multiple reflections recombining in space and producing a trough in the location of the receiver. Worse, parasitic phase shifts (multipath) can scramble the OOK signal (which is the most common modulation for remote control) making it unreadable, while the signal level at the receiver is adequate. BTW wall mirrors such as those in bathrooms can play havoc with the RF.
