I used the product to on a 50cc Dirt Bike to help it make it start up the engine. The website did a good job on taking pictures which showed the exact measurements which help me BUY the item. It arrived in PERFECT Condition and it arrived on the date it said it would. The DRIVER did the COMPANY a GREAT JOB. It said ten at night but he got it here at 11am had the boys riding the dirt bike by 11:45am. It made them smile and it made my day to see that smile on thier faces. ... show more
