They spend quality time with each customer to make sure they find what they need and also will answer any questions you have. I came in there because my brakes were squeaking. I just had them checked so I know I didn't need to replace the pads. They showed me a brake pad and what could be causing the squeak and what I could do to fix it myself. I opted for this spray and it worked, no more squeak! I didn't give them 5 stars because the price is a bit more expensive than Walmart, but Walmart automotive barely has anything compared to AutoZone and AutoZone has the staff to spend the time with you to answer any questions you may have.
