Peer Testimonials

Coach Cam Frick

“The Armilla Tech Baseball product was a game changer for our team. It allowed us to communicate signals to our players in a way that we knew they would understand while knowing the other team would not be able to decipher.”

Coach Juan Morales

“I really liked the system, it is fast and loved that it does not rely on Wi-Fi. The system will help educate players and keep the bench involved in the game. Armilla protects my signals from being stolen. The product is affordable and easy to use. It is going to help the game of baseball”

Coach Jorge

“Armilla is very good system and will improve the game and plays. This system will keep my signals secure. I liked how I can move my outfield in/out/left/right without having to yell at them. My messages and plays are sent within milliseconds to my players. I could send custom motivational messages to my team and the best part is it took 5 minutes to learn the system.”
