I don't think I would go out of my way to buy them... I got mine as a gift. But they serve there purpose.
I have the same set and I came to possess them in the same manner. That set lives in my van, along with a pattering of other tools, including a wrench set.
I expect the goofy pass through Craftsman to perform well for basic repair items I would expect to do in my normal travels (alternator, shocks, etc), but when it comes to what would be considered a major roadside or trailside repair, well, they wouldn't hold up. I replaced the ball joints on my van this weekend, the original set pressed into the spindles 13 years ago came out after a long battle that included me fabricating a heavy duty all steel work table to remount my bench vice because I broke it free from my sturdy wooden work table while using a 4ft long cheater bar to turn the ball joint press with a 1/2" drive breaker (including beating the business out of it all with a BFH). That pass through socket set would have broken and possibly (by some chance) caught on fire during all of that.
There's guys who carry emergency stick welders and there's guys who only carry a spare set of sunglasses. Somewhere in between would lay most of us (I would guess) and in that manner we have to determine to what length we're going to be repairing our rigs while out. Some of that comes down to having a solidly maintained rig before backing out of your driveway, some of it comes down to using some of the HP between your ears while driving. The rest comes down to luck and how much risk you would expose yourself to if you had a catastrophic failure. Solo expedition across northern Alaska? Ok, carry your ARP bolt tool to replace a rod if you toss one. Group drive across a popular forestry road? Maybe double check you have the local repeaters programmed into your HAM radio?
