The general quality of this case is good, considered its physical protection, this case could seal the deal and protect your precious guitar from any harm.
The only reason I put three stars on the total score is because there is a closing gap in between the plastic parts, even you have all the latches closed. And most importantly the gap is not negligibly small.
I try some old-school method such as clamps to press both side and leave it for several days, but still have no effect disappointingly. In this case, I would not say this is 100% rain-protective. However, in any situation, i will not take it outside if it is raining anyway.
In summary, I think SKB should have this flaw fixed, otherwise I see no reason why this case should charge this high with this price. From the photo, you can't see how large the gap clearly, so it is not fair to us without knowing that this case has such a problem.
