Portable Upright Double Bass Cart Bass Buggies with Wheel Transport Carry String Bass Carts for Any Size Bass from 1/10 To 4/4 Works Indoors &Outdoors (Bass Cart)

I'm sure this is great for "indoor" mobility, but not sturdy enough for outdoor festivals or "off-road" events when you want to take your bass with you from jam to jam. I returned it after using it for 3 minutes. It wasn't a piece of junk, but not quite what I had in mind...
