During the pandemic Iï¿½ve done a good bit of home mechanic work for friends. This was my first stab at PF BB. Tool worked flawlessly and appears to be constructed sturdily. I can see where the pro tool may have broader applications and quicker execution but neither were needed in my application
If you need to replace Trek BB90 bottom bracket bearings, and want to make sure you don't ruin your frame or new bearings, this tool does the job perfectly. Wish I had purchased this years ago.
