I purchased this tool a few years ago. I have only used it about 6 times. I pulled it out of its case to adjust my seat the other day in its almost brand new condition. While setting the torque, the head did not 'snap' as a torque wrench of this type is supposed to do. I verified this many times and after re-setting. I attempted to contact warranty support to utilize the advertised "Lifetime Warranty", but keep getting a non-deliverable response to my inbox. There are no other ways to get a hold of the company. I spent a lot on this tool hoping it was a quality brand, and now cannot even utilize the services promised upon purchase. I will be buying Park tool and other brand named tools in the future and am very disappointed with the whole process with Pro Bike Tool!
