Speed StacksSpeed Stacks G5 Timer | Official Sport Stacking and Cubing Association Timer | Accuracy to 0.001 seconds

My kid loves it. He's a "cuber" now, so this was his Christmas wish. He said it's down to the second. If your kid is a cuber, you can ask them what that means.

My son recently got into "cubing" and he loves this. It keeps the time well and he's excited to use this to improve his times on completing rubix cubes. Overall great - it's holding up with daily use and no complaints.

We bought this timer for a 10-year old who is into Rubix cube and seeing how fast he can solve them. He loves it. It kept him occupied on an overseas flight for six hours. The value for the price was well worth it.

The media could not be loaded. real good timer but smaller then expected

It was great.

It's sensitive in a great way I think it goes down to milliseconds

Despite what what many reviews say, it is fairly easy to connect this device to a computer. It is just hard to figure out without directions because it sends the time data to your PC via audio cable.Instructions:1) Purchase a 2.5mm to 3.5mm audio cable2) Plug in the 2.5mm end into the timer and the 3.5mm end into your computer microphone jack (note the microphone jack is NOT the same as the audio jack, you may need to buy a microphone to USB adapter if your computer does not have a microphone input)3) Go to cstimer.net4) Go to Options --> timer --> "entering in times with:" --> and click "stackmat" (see screenshot)5) Go to Tools --> Function --> stackmat --> Device --> and select the proper input (see screenshot)6) Everything should now work! You can even link to your Google account and save your times.
