So I bought these about a year ago as of summer 2018, on account of my old boss having a set. He preached that they were awesome. Ultimately agreeing that for the price, unbeatable, I bought a set for myself. His are an older model. These being newer refresh, I thought, these are gonna be the kitties t*tt*es. D@mn, was I wrong! First went the 12mm. Started skipping maybe 8 months after purchase. Took it easy and figured maybe warranty it. Complete failure maybe a month and a half later. Followed closely by the 14mm and now my 10mm. A 10mm used to loosen 6mm bolts. Joke! All 3 heads started skipping (knuckles will suffer) and will eventually all end up like the 12/14 wrench. Pounded to ish and chucked over the back fence, over some train tracks and hopefully in the junkyard over another fence. P*ss poor quality metal in the heads of these wrenches. Def won't last used every day. If you're a professional and need high quality tools, this ain't it. If you're a home gamer, this ain't it. If you're looking for a nice gift for your handy significant other, this ain't it.
