"Excellent Economy Reusable Engine"
Hulksmasher123
This is actually pretty good for its price. It's refillable so technically it can be used forever or until it breaks. So far I've refilled this 7 times and used it 7 times. It doesn't look to be breaking any time soon.

"Hits hard, plus a good sustaining thrust"
Larry
I've used G64's for approximately 25 years, and it's a great motor. The thrust curve of the G64 is nearly perfect in my opinion. It hits hard and can have a 2-pound rocket moving at very stable speeds (45 ft/sec) at the end of a 5 or 6 foot launch rod. After the initial punch, the thrust tapers off due to the C-slot grain design, providing a nice, long sustaining thrust. The only downside I've encountered with White Lightning propellant is that it can be difficult to ignite at times. A thermalite booster can be helpful in this case.

 
"Greatest bang for the buck motor!"
reytech
Has to be one of the best 'bang for the bucks' reloadable 29 mm motors, in my opinion! The White Lightning propellant produces a big, bright white flame and lots of smoke! And a nice very audible sound as soon as it ignites! One of my favorites.

Comments
