I have tried one...they break pretty good....the jump part actually takes a bit of work...
For less money I got a Terry Mcfadden Jump/Break that outperforms (to me anyway) the Samsara in either catagory.......and blows it away in the jump catagory....actually the Mcfadden outperforms quite a few strictly jump cues....I can even jump balls with it...and I aint no good at jumping.
