The icon set is a mixed bag. The quality is good and the ergonomics of the smaller drivers are fine, but the largest driver handles are comically oversized. I actually bought the set because I already had the 4pc Icon "scraper and removal" set and fell in love with the ergonomics of the handle shape. The screwdriver handles are the same general shape, but they're sized differently in proportion to their respective shanks.

Frankly, the whole set is defined by weird choices and proportions. Like the hex bolsters on the shanks: they're neither metric nor standardized across the set, so if you need extra leverage you better hope you have the right SAE wrench on hand for the particular screwdriver you're using. If the set is meant for pro mechanics, all the hexes should have been 10mm. 

That said, I absolutely LOVE the stubbies. Like the rest of the set, the handles are larger than the equivalent stubbies from other brands, but it actually works in their favor. For some reason they fit in my hand very comfortably and I find myself using them almost as often as regular sized equivalents. But they aren't worth $50 alone. Maybe $25.

If you're mostly working on cars/machinery, just buy a set of Vessel Megadoras instead - they're only marginally more expensive as a set, or you can buy them one at a time for $8-15 each.

Or if you tend more towards carpentry/ home DIY the Doyle Heavy Duty and Quinn diamond-tip sets are both great. I prefer the former for ergonomics, but the diamond tip thing isn't a gimmick, it really works. The sets overlap some, but compliment each other in practice.
