Bought this as part of our hire stock. Delivery great, product good. It's well made, but I'd question the 30kg load capacity, used with a box which weighs 28.5kg and it felt a little too on the edge for my liking, when stands are winched up it was just a touch less sturdy than I would have liked. That aside, when used with our other enclosures at 22.5kg and 18kg it felt very sturdy. Bottom line: very useful, very good for the price, but I'd avoid anything on the limit, especially if you're raising it very high. 4 stars is about right!
