They are quite possibly one of the best values in cues.
Don't get me wrong, the quality is lacking, paint is chipping off at the joint on mine and the weight bolt is off center (it will actually make a full roll by itself if started correctly)
That being said...I put a Samsara Break Jump tip on mine, it crushes the rack, it jumps effortlessly and you can connect just the rear section of the cue to the shaft for longer more controlled jumps.
Great cue for the money.
