We use 2-way radios at our store for the cashier and gas-pumper to communicate. It greatly reduces drive-offs and we don't do pay-before-you-pump since we have a pumper. But, we've gone through probably 10 sets of radios in 3 years. Midland, Cobra, Motorola, you name it. We've gone cheap ($50 pair), to moderate ($90 pair) in price. And, it isn't that we're damaging the radios; oddly enough, they just quit working. Either the volume control will go away, sound will quit, transmissions will fail, you get nothing but static on all channels and all settings ..... I mean it is always something quirky and different.
SO, I need someone with some experience using 2-ways to give me a recommendation. We'll spend a couple of hundred bucks on a set if we can be sure they're good quality. Our guys wear them on their belts with a clip.
