5 of 5 Customer Service August 15, 2019
: Damien St James from Keene, NH United States  
Outstanding customer service. Mas Defense was very personable, professional and prompt with delivery. I called with an order number after hours and a gentlemen picked up the phone. He proceeded to look up my order and addressed the question directly. Mas followed up the next day to ensure my billing and shipping information was correct. The company seems very organized and the quality of the product exceeded expectations. Not a scratch on the finish and it appears their quality control and communication is superior to other online retailers. It’s refreshing to work with a company with its act together. They seem to have pride in their product. I don’t normally take the time to fill these reviews out but I have respect for this company. I will return soon and I will be recommending MAS to members of our shooting clubs.
