    quality to cost, these are a great value. I am very happy with Sunex products. I do not have an issue with the driver receptacle end being flat. I know some other folks dislike that there drive receptacle isn't beveled like other extensions, but it makes zero performance and functional difference.

    Sunex impact extensions & sockets can definitely hold up a little better than Snap-on impact stuff in regards especially to the square drive end.You're not paying the $130+ for a 5 piece Snap-on extension set! FACTS!!!
    Strongly recommend to any hard working mechanics out there!

    Sunex is an amazing tool company. The quality of these impact extensions rivals anything else on the market for a fraction of the price. No; they are NOT attractive - ugly black unfinished metal - but functionality wise; they are Awesome! I was leery that the ends might shatter the first time I used them. But hundreds of uses later, and they are still going strong.
