Not a scuff or scratch in sight anywhere. Received the kit and was field ready out of the box. You can spend more money, but you can't get a better gauge for the money. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars the 5- valve guage *by L***N on Reviewed in the United States on September 7, 2013* another industry classic... if they can find a way to get you to spend more money - they will- the plastic case should've been heavier guage, and less like a fishing tackle box ### ⭐ 1.0 out of 5 stars Cracked manifold *by S***H on Reviewed in the United States on May 27, 2018* I just went to use this product for the first time today, and it has a cracked manifold. It appears as though it has been frozen, frustrating! Trying to figure out customer service and warranty repair is painful!
