The SpeedStacks G4 Pro Timer works on batteries and has the power, save, reset and next buttons around the display. You can carry the timer along with your Rubik’s cube anytime anywhere. It is a great buy if you love to solve cubes whenever you feel like. It uses infrared technology to detect your hand motion to start and stop the timer. The best part about the YJ Pocket Timer is that it does not require any actual pads. The front face of the timer has the reset and the function button. The right side also has an auxiliary display port which can display the timer on a computer or any device.

The power switch toggle is placed on the left side along with infrared sensors on both sides. It is relatively smaller in size, can fit easily in your pocket and also works on batteries. The YJ Pocket comes in great colour options, but that’s not all. It is a well-built model and has better functionality than the QJ Timer. The lights on the screen flash as the timer runs and stop when the timer is paused. The Qi Yi Timer works on batteries and has the power as well as the reset button quite largely displayed. However, the bottom section can be easily parted as it contains magnets that can stick to the mat. The back of the Qi Yi Timer has foam pads to protect the bottom. It also comes with a cable-one end of the cable plugs into the timer and the other plugs into a headphone jack. The QiYi Timer records up to a hundredth of a second. It is affordable and quite comfortable to use, especially if you are just starting out. The YJ Timer works seamlessly with display and CS timer. So, the timer would begin as soon as you tap on it. What’s more, is that the sides are pressure sensitive. There are buttons on the top – power button, save button and the next button. Therefore, this is definitely quite a great upgrade. A surprising fact is that the reset button is hit by mistake at times in Championships as well. This is a great deal so that you do not hit on it by mistake and lose your time data.

The reset button is situated towards the bottom. The YJ Timer comes with little nubs on the back so that it can sit into a mat.
