Junk!! Just kidding, every manufacturer has a dud slip through fro time to time. It's when you crack the same model three times in a row that it's a problem. I did that with an Adams 303 stainless a long time ago. That really was junk. Good job TM for making it right.

I cracked the same Adams head as well! I actually liked the driver though.

I get the impression there seem to be a number of posters who think that cracked clubheads should never happen or that they indicate some question of quality of a head model or a company.
When you design and manufacture high performance, thin walled, high COR clubheads, you are walking on the edge of failure with every head you produce because the tolerances for all the wall thicknesses are so thin and there is a lot of welding that has to be done with a high level of precision on all these heads. And all that has to be done within a very strict budget because there is a limit to what a golfer will pay for a club.
Statistics known by designers and product development people from working with head production factories indicate that within such high performance clubheads, if the failure rate is more than 1/4 of 1%, that is more than what should be seen and something is wrong. If you get your failure rate to be less than 1/8 of 1%, that is considered to be really, really good.
Obviously, the higher the clubhead speed of the golfer using the heads, the more stress is put on the heads and the more chance for failure. This is the obvious reason why people with clubhead speeds north of 110-120mph see more head cracks and failures than those with more normal head speeds. But no matter what, it is possible for a head to fail for a slower swing speed too, if that head just happened to have a mistake in the attachment of one of its construction parts.
The misperception comes from golfers who happen to get that ONE head out of 500, 600, 700, 800 or 1000 that happens to fail. You didn't see the other 499, 599, 699, 799 or 999 heads that go on repeatedly pounding the ball down the fairway so when YOUR clubhead cracks, it is easy for you to think the company has a problem or something is amiss. For companies to reduce failure rates substantially from the norm would cause the price of production to increase dramatically such that fewer people would buy new clubs.
The golf industry does not X-ray its welds as does the aerospace industry because for one, people's lives are not at stake in the event of a welding line failure in golf - and because such additional inspections just are not cost effective in the face of the normal statistics for head failure and what the market will bear for the cost of golf clubs.
Believe me, there is not one designer or product development manager who does not cringe or get nauseated when they hear about failed heads. I certainly do when they happen to my designs. We all know you golfers think badly of us and our companies when the law of averages camps on your doorstep and makes you one of the statistics.
Seriously, making high performance, thin face, high COR, multi material clubheads is a real challenge when you think about the many production steps that all have to be done with very high precision and very tight tolerances - and then when you think about the stress to which these heads can and are subjected. But that's the tightrope we all have to walk to be able to provide high performance, thin face, high COR, multi material clubheads for golfers.
In the golf equipment industry, there are head production factories that a designer will NEVER EVER consider for making high performance, thin face, high COR, multi material clubheads because you know that is not their strength and expertise. When you find a factory that can do this, you tend to camp on their doorstep for your high performance designs and you sometimes lose a little sleep hoping they don't develop problems in their day to day operation that might adversely affect the production failure rate.
In short, it is REALLY difficult to produce high performance clubheads with the utmost consistency and I think most golfers just don't appreciate the skill that takes. I know in my case I would never want to change jobs with the guys who manage production in these head making factories. That's like keeping 100 plates spinning all at the same time and always watching for the next one that's about to wobble and fall.
So the next time you get a head failure, just shrug it off and go through the inconvenience of asking the company for a replacement. All good companies will never question you and will always work hard to get that replacement in your hands as soon as possible.

Excellent post! I remember back when graphite heads were the thing that a lot of the high SS crowd were having head failures right and left. Same problem. These players are stressing the heads to their limits and any tiny imperfection will end up as a failure eventually.
With these newer heads, I'm also curious about contact point on the clubface. For instance, the post above shows a crack along the top of the face. Many tee the ball quite high these days and tend to contact the ball on the upper half of the clubface predominately. I wonder if the repeated off-center contact can be contributing to the failures. Also, the OP mentioned that his clubhead was dented near the toe. Another off-center contact perhaps. Something to think about. I'd be interested in some ball contact tests done by these guys to see where their regular contact point is.
