My experience was pretty bad. I went in for new set of tires and they broke the air sensor on all four tires. They tried telling me that they couldnt do anything for me but replace them for an additional sum of money. I was left with little choice but to leave with the problem.
Honest and free opinion.
I took my car in for an alignment, and instead was informed of numerous suspension problems. Sensing my suspicion, the mechanic invited me to step under the car and explained everything that was damaged (stupid IL potholes).
I ended up deciding to junk the car after talking it over with the staff at Cassidy's. They didn't charge me for their time, and I'll be back if I never need tire or brake service in the future.
