Just bought the one size to carry on my bike for adjusting the handlebars. Good but pricey!

I snapped the no-name brand hex that I had and purchased this one to replace it. This one had no issues loosening the bolt and didn't break. That's what you get when you buy a better quality tool.

Works fantastic. Love these working on my bikes. Get more torque! hang great from my garage wire shelf.

4 mm is a common size for bicycles, and that’s what I bought this for. I like that it DOES NOT have one of those rolled ends on either side as those can strip hex heads. Good tolerances. I’ll be grabbing 5, 6, , and 8 mm wrenches based on this purchase.
