This gig bag is excellent value for money in my opinion. The zip is heavy duty, as is the bag material itself. The design is well though out, allowing for storage of extras, such as sustain pedal, leads and a power adaptor. A divider for the inside is included, with Velcro fastening, which allows partitioning of items which may damage the casing of your piano. The padding of the gig bag is sufficient for transporting in a car, or by hand, but it would not stand the rigours of touring or protect your equipment safely as a flight case, although this is not the intended purpose of these budget bags anyway.
I contemplated spending a little more, to protect what is an expensive and unwieldy item, but I am very happy with this.
