As an electrical installer I've tried pretty much ever repeater out there. Usually I do installs to improve signal in whole buildings, homes/offices etc using Wilson Electronics repeaters, which are in my opinion the best around. I've tried these Cell Rangers too, but they are a different product really. These seem to work pretty well to give you a small boost in a portable package. In my tests my iPhone gets a pretty reliable 25dB gain and data is noticeably faster.

Obviously these products aren't a viable solution for an entire office building, but they shouldn't be criticized for that. To cover a 5,000 sq ft. office my equipment costs (Wilson gear) would be around $1,300 - Around ten times as much as the Cell Ranger.

$150 for an extra 2-3 bars is decent value. Don't criticize them if you have no external signal and they can't get you signal coverage over 2,500 sq ft luxury condo. You have to pay a lot more for that.
