2. **Limited Range** Wireless doorbells usually have a range of 30 100 feet, depending on obstacles. If the chime unit is placed far from the doorbell, signal strength may weaken.

3. **No Smart Features** Unlike modern smart doorbells, this model does not integrate with voice assistants (Alexa, Google Home) or mobile apps for remote control.

4. **Basic Functionality** Lacks advanced features like video recording, motion detection, or two-way communication, which may be desired in some applications.

5. **Potential Chime Fatigue** With 48 chime options, there s a risk of users growing tired of the sounds over time, especially in educational settings where repetition occurs frequently.

6. **No LED Indicator** Some wireless doorbells include an LED light to confirm activation; this model may not have that feature, making it harder to verify if the system is working.
