I really like the quality of mine. The docking hardware fits really tight and there is no rattle with my pack. The tether is weak and may need to be replaced but you can get a Drag Specialties tether for $14.00. The lid closes tight and although I haven't tested it I don't think any water would get in. I read a review saying the latch could be a weak spot as well so I lock my tour pack when I travel to avoid the lid opening on its own, but there again a new latch isn't a lot of money and may be worth ordering a lock to match your bike anyways. For the price I really don't think you can miss with these even if you spend the money on OEM hardware you are still way ahead.
Now if you need a certain colour you may want to check out Advanblack or Nastyhog.
I have had good luck with the TCMT versions of stuff I bought. Fit and finish has been spot on and my painter has had no complaints on them either when I've take the stuff to him.
