The Crystal Shift Knob with Touch Activated Ultra LED Light is a unique and stylish addition to any car interior. The knob is compatible with most cars that have a button-less operated shifter and can provide a touch of luxury and sophistication to any vehicle's cabin. However, before purchasing, customers should note that the LED lights cycle through colours and cannot be stopped or customised in any way. It may be a downside for those who want to tailor their car's interior to their preferences. One minor drawback is that the charging cable that accompanies the product is short. But can last up-to 5months when fully charged. Overall, the Crystal Shift Knob appears to be made with quality materials and is a unique addition to any car's interior.
