What Customers Say

Trevis V -- I made one phone call and told them what I needed and that was it. I mailed it to them. They called and told me the price. The next thing I knew we had our machine back. No hassles. Thanks.
Sal G --I was very satisfied with the way AlcoPro conducted this repair all through the process. It's great to see a company that backs up it's products 100% and goes the extra mile in pursuit of customer satisfaction. Also as a law enforcement professional I need to have my testing equipment maintained and ready for service as soon as possible. AlcoPro made this possible. Thank you!
