I think you will be very happy with them. Like I said, I use to have the T-handles and while I like the way they look and easy of removing valve covers, I am very anal about them and I hate how they look if they all don't line up the same way. Drives me crazy.
Now, I have these and I think they look just as good, if not better plus, they don't get in the way, I don't have to worry about if they are lined up, and I just keep a T-handle Alan wrench in the tool box.
