This is a very easy stringer to use. I have used alpha and gamma at college where I play tennis. Eagnas is a far better company. This machine is great for any one who wants to string. The setup was very simple and the machine is very sturdy standup. It does not tip or wobble when you move parts of the machine. The clamps hold the string very well and can be adjusted without a wrench. I recommend this stringer to all.
