The last socket I had that split was an old US made Craftsman socket..... But it was replaced free of charge.
I have a smattering of mid-grade (not Icon) HF hand tools. Wrenches and sockets mostly. The only real issue I've had is with their wobble extentions where the end that fits into the socket breaks off after a few years of hard use. Always replaced for free and given the design, it really isn't a surprise when and where they break, but they sure are useful.
Their hex driver bits have worked well but tend to be slightly softer than I think they should be and thus get loose after a number of years of good use. I am absolutely pleased as punch with their ratcheting end wrenches, been using those for years and they work very well, fit the fasteners very snug and the ratchet action needs just a few degrees to click to the next step.
For those rarely used but necessary tools I typically just watch ebay, some really good bargains there. I got a set of Craftsman flare nut wrenches, both SAE and Metric in the same bundle, for like $20 brand new. They are as good as the SK set of SAEs I have up at the shop and obviously cover more of my cars. Most of my mainstay hand tools are Craftsman, the older good stuff.
