Honestly they're just cheaper aluminum TBB's. Basically the same as the Madbull ones (not to say that Madbull is shitty). If you want a good TBB that's going to last and help your guns performance, look into getting a nice steel one. I bought a Bravo steel TBB, and it helped my gun a lot, but if you want a great barrel, look into Prometheus or PDI.
