I use it for my Hartke LH1000 head, have to say that fits perfectly and I have even got some extra room at the back which can be gently used for cables. It does the job that a flight case is supposed to do, but there are some parts where the wood won't ever be tight to the edges or corners....
Wood does not feel 100% firm but again, for the price you're actually getting a good product that will definitely protect your gear.
