You can buy the elastic bands alone cheaper and come up with better set ups than that. Titleboxing sells an overpriced one like the one in that video.

can it improve on speed and punching power

Not the way that he's using it. Check out Von Milash's powerjabber 3000, or Scraps elastic setups in the Important / Useful posts section. I hope this helps. ;)
