Overall sentiment: negative
Customer reviews:
Did nothing for performance plug Head burnt out with in 200 Miles trash 
 China junk! 
 The cdi box smoked as soon as I tried  to start  it. My son had the same thing happen to his. I put the original  one  back in and it ran fine. I haven't used the sparkplug  or the coil yet. 
 The spark plug electrode melted after riding 15 minutes. Good thing I had an NKG on hand. The coil and cdi seem good. 
 Do not buy. Scooter slowed down and also got a lawnmower plug instead of the one pictured. 
 Well no improvement... Coil misfires, the cdi actually made scooter run poorly, plug IS NOT A PERFORMANCE 3PRONG  (the one they show or describe!!!!!!  Waste of money however cheap... Save yourself a huge headache trying to tune with these and get stock... DON'T BUY FROM THESE CROOKED PEOPLE!!!!! 
 Garbage. CDI was bad out of the box. 
 This item did not work when received, had to order from another company 
 This fixed my GY6 go cart! runs so much better now, maybe added a slight bit of power too, but its hard to tell.
UPDATE: This is total crap, it stopped working within about a month. Bought another more expensive brand hoping for better quality. 
 Listing claims to fit sunl go karts. The ignition coil wire is not long enough. The cdi box does match the wiring harness but will not fit in the mounting box. 
 Did Not send the cdi advertised,it is orange ,no pigtail ,and doesn't work,no spark,not worth shipping back,will keep the plug as backup to my ngk .coil wire seems to work,but cant tell if better than stock since the cdi I currently have is stock ,will no longer buy direct from China 
 Wire was useless 
 do not work vary good the led lit on cdi box don't work end up coil end broke just on happy 
 I did not get a 3 prong plug and the cdi unit would not work. I would not sell these kits to any of my friends.
