What Customer Say


  • After talking to sales people at various companies, I stumbled onto WeatherShack.com and called your sales number. The guy on the other end of the phone immediately gained my respect. He was knowledgeable about wireless weather stations without being arrogant... He questioned me with deft skill, seeking out what I needed, not what he could load me up with. He made sure at the end of the conversation that I had the weather station I needed and more importantly, that I understood what I needed and what I had just purchased... You guys are the barometer for which others in your industry should compare themselves.

  • "I just wanted to say a big THANK YOU to one of your customer service guys. I deeply appreciate the help I received, the very quick response and the fact you could easily have sold me a part I didn't need. We have gotten used to our weather station to let us know the temp outside. I really recommend these products and this company for the first class help and service. Thanks again for all the help and for being a company and employee with integrity.
