I required a "light" case so that I could take my mando on an aircraft more easily. In reality, this case is only marginally lighter than my hardshell. It's also slightly longer. In the end I took a cheapo mandolin in a very basic case and just took care with it in the overhead locker. If I was taking a higher end mandolin I'd probably take this case.
Inside it's just like any other case. There's not a lot of room for a strap e.g. I have a leather strap with a padded shoulder pad and it just about fits in the compartment inside.
The zips seem quite sturdy and the only issue I have is that they do tend to catch on the lining at the headstock end of the case.
The front pocket is meshed so that you can see what you have inside, but there again so can everyone else. Taking into account the size of the instrument the pocket is quite generous but you'll not fit much more than an A5 music book. Nevertheless a few plecs in a little pocket wallet and a tuner etc. fit quite well.
The best point about this case is that it comes with straps. The downside is that the connecting hooks don't feel overly strong and the straps don't feel particularly strong or well made. So far I've taken it to one festivel and the case, and the mando, survived.
When I started looking for a case it became apparent that there's not a great deal of choice in the "light weight" sector. I think that there must be better, lightweight cases than this and when I do find one I'll get rid of this one.
Overall, apart from the straps, there is little to be gained by having this case over and above a hardshell case. It's marginally bigger than my hardshell (Kinsman) so what you gain in the (alleged) lighter weight, you lose by having a larger case.
Average.
