The best thing about these wrenches is they are true to size, and dont round off bolts like many Allen wrenches do. They are also very comfortable to hold, and have a solid feel in hand. The wood case is cool, not sure if I would rather have one of the Silca travel pouches though instead like the T-handle wrenches they make. They make working on a bike that much more enjoyable, especially if you have a high end bike with unique fasteners (as many do) that you dont want to round at all while making adjustments, for fear theyd be a hassle to replace if you had to. They are expensive, are they worth it? Maybe, if you keep them and pass them along to your son so he can enjoy them for future bicycles he may work on....
These hex wrenches are expensive, but worth every penny. Like a lot of riders, i spent a lot on my bikes and gear, but i skimped on the quality of my tools and boy did i pay for it. These wrenches fit exactly. No more stripped heads fir me!
