    Exceeds Expectation

    The build quality and functionality of this Gamma Progression II ELS stringing machine absolutely blew me away. It's so rare to buy something that solidly exceeds expectation. It's easy to use and works perfectly. It was completely pre-assembled; all I had to do was plug it in. The directions that come with it are well written, and I found a few YouTube videos from other users that helped get me started. I couldn't be happier.

    Good string machine!

    Gamma ELS Progression II Stringing Machine

    I have had two or three different machines now, all of them very good, but this one is my favorite. Made out of quality parts and built to last. The design is smart and efficient - allowing me to do a quality stringing job in a relatively short amount of time. Absolutely love it.

    Tennis Machine Pros was quick to answer my questions and got the machine to as quick as they could. I would recommend this company to anyone looking to purchase a stringing machine.

    Great Customer Service

    My buying experience was top-notch. Due to the COVID-19 Pandemic, I had to wait several months for my Gamma Progression II ELS to ship from the manufacturer, but throughout the entire time the Sales Representative from Tennis Machine Pros kept me updated on the status and progress. The machine arrived in perfect condition, and although a Starting Clamp was was inadvertently missed in the shipment, I have no doubt that TMPs will make it right for me. I highly recommended TMPs!

    Hi John, I don't believe your order included a starting clamp, but we will happily be sending you one free for your great review. Thank you for your business!
