Product Description

Speed Stacks, in partnership with the World Sport Stacking Association is excited to announce a big step in the evolution of sport stacking. If you would like more detail about how this will impact tournaments and records please check out The WSSA announcement at

Get the best of everything with the Speed Stacks Ultimate. Includes one set of Speed Stack Pro Series cups (or your choice of any cup color), a StackMat Pro (G5 Timer and Gen 5 Mat) and the Stacker Backpack for holding everything.

Speed Stacks® are specially designed high-tech Sport Stacking cups endorsed by the World Sport Stacking Association (WSSA) for competition. Speed Stacks are the only products approved for use in WSSA sanctioned events and each cup carries the official WSSA seal of approval.

The G5 timer has two modes: 4-Pad mode (for stacking) and 2-Pad mode (for speed cubing, where it operates just like a G4 timer). To switch between the two modes just hold the RESET button for 5 seconds. To ensure 2-Pad mode doesn't get used at stacking tournaments, in 2-Pad mode the display and the TD blink the final time three times so the operating mode is obvious to judges and spectators. The LCD display and the LED color also indicate the timer mode. Two pad mode can also be used by stackers with motor control issues that prevent them from using a four-pad timer. G5 timers are compatible with our Pro Tournament Displays.

Take Your Stacking To The Next Level! Pro Series cups are endorsed and signed by World Champion Stackers.

  • No center that eliminates air resistance and reduces down stacking time
  • Special high impact material
  • Official WSSA approved equipment

Amazing. November 15th, 2014

These cups are great. I was introduced to them by my friend Jesse and now I can't stop stacking. I haven't broken a single cup and am amazed at the quality. These cups are worth the money (but maybe buy something cheaper to START)! Now, I average world class on almost everything :D! My life is SO MUCH BETTER because of this amazing sport. (YES, it is a sport.) Thanks so much! :)

Super Cool, Great Quality, FAST Shipping February 4th, 2013

We just received two sets that we ordered last thursday (31st of jan, evening). And received the two packs for our 8yr old and 5yr old today around noon. Delivery status when ordered said 5-7 business days, they arrived after TWO days, great! Kids LOVE the Speedstacks, they are constantly playing with it, they watched the DVD that came in the box several times and it helps a lot. (Was a free gift I guess...?)
Thanks guys for keeping my kids of they 'r iPads, lol. Overall GREAT QUALITY, I think these sets will last forever I guess. So if you 'r reading my review right now, just go for the ULTIMATE pack, no doubt about that this is the way to go. It comes with all they need to have a lot of fun with it and again the quality is PERFECT. What 's 45 bucks these days, filling up your car is more expensive, or five tall coffee 's at Starbucks correct? My kids are VERY HAPPY with them... Good luck
