Hull Storio2 purchased to protect my son (almost 5 years) attentive but awkward. Simple setup place, all ports remain available (except the game cassete but he plays long enough with the same tape before changing, change mom or dad). Important to him, the stylus remains accessible, as well as allowing the foot to hold the upright console.
The protection provided appears to be correct, although I prefer leaving the organization of a crash test session at whoever feels called ...
Cheap protection for a fairly expensive product, so highly recommended.
