Toilet Repair Fail

Just a heads up for those working on home improvements this summer. I have a toilet that needed the insides replaced. I picked up a Fluidmaster 400AKR "Universal" repair kit from Home Depot (arguably my first mistake). I've replaced the insides of a toilet tank before. It's not rocket science. I tried 4 times to get everything to seal properly, but the flush valve kept developing a slow leak. Then I started searching for reviews on the product and found the manufacturer is pretty much a seller of cheap crappy parts. I'm off to take this back to Home Depot. Frankly I'm thinking of swearing off Home Depot all together. A lot of what I've gotten there as been complete garbage and items from local stores like Dirks Plumbing and J and J Garden Center seem to never have any problems.
