How does this product fare with customers? Do they experience fewer to no drop calls? Let’s find out:

James: “I live in an area that is about equidistant between cell towers. My best signal strength in the house is 2 bars or less. I lost calls all the time, sometimes just because I pivoted while talking and placed my head between the phone and the tower. The lower level of the house is partially sub-grade and I can never rely on maintaining a connection.

This extender has solved all the above problems. I have a clear conversation now, but no increase in cell strength (still 2 bars), When I turned it on, the phone showed no bars and thought I was too close to the repeater, but reception was clear. Routine contacts have commented that my voice is not choppy as it was before. I can definitely recommend this product’s signal boosting capacity.”

Liam: “Very happy with this product. We live at 3700 feet and appear to be above cell signals, which seems odd, but this product brings the signal to our house and allows us to make calls and receive calls!! Woo hoo! I am ordering another for a guest house that we own/run that is in a hollow at the bottom of the mountain, so that our guests will have service too!”

The zBoost Wi EX ZB645SL-CM retails for only $464.95.
