lol u should have interviewed people who actually use it every day. My fiance UK and I USA use ours all the time and it really helps with the distance. We have the old model now for 3 years and about to upgrade to the new.
I've been looking into this myself commenter :) Looking to get one of these for my wife, so we can feel more safe being able to get eachothers attention fast. Do you find the Bluetooth functionality to be a hassle/ Any charging problems or problems with the make or quality of the materials?
