Product review (4 stars): Really worthwhile if you have a broken stud. Make sure that it fits your particular model.
Not so easy to install but it did replace a broken stud and I am able to use my shelf again. Thanks to this re-seller I did not have to call a repair man which would have cost me an arm and a leg.
I wish I had known that this retailer was within a reasonable driving distance and I could have picked it up the same day.
In any case I got it and it works just fine.
