The product is well designed and the price is very reasonable. However, I would caution anyone using this product to ensure there is adequate clearance between the inner fender and the front of the engine. I used this on a 2006 Malibu and there wasn't enough room to line up the bolts and start when reattaching the timing chain to the water pump. It was like building a ship in a mirror bottle. If you're short on space, use another crescent-shaped mark instead of a full circle like this one. I bought this because it keeps the bolts from falling into the motor. The downside is that this limits access to leveling and bolt firing.
