What do you think Honda will say when you take the new one back? I think it's grounds to get your cash back. Then you can buy one that doesn't leak.
I think the side boxes are OK, but the zip on the top box doesn't look good. When they first came out, I heard some people talking about security - that you could cut through the material with a knife. I've haven't heard of it actually happening yet but it may worry some.
Apart from the top box leaking, I think they are way overpriced anyway. Not one of Hondas best accessories.
