Perfect fit for a Roland S-1608. is more than a 3units?s Rack fits perfect , shallow size... very very comfortable, very handly.
Very usefull the back side with zip to put extra staff,short cables,adaptors..
Is made in hard plastic mostly, but kind flexible if you squeeze it (take care), it have extra plastic (not metal) square frames inside the handles(look inside and at the sides and corners) to reinforce the case, to attach the handles, works pretty nice.
Is thin if you compare with a normal case ( is plastic)
The butterfly road case locks, looks like are the cheapest.
The prize is very attractive. The product is a must have
