Sandbag was exactly as described, double-zippers are perfect.
Excellent customer service!
Well built, and works as advertised.
Bought 2 of these for my Strobepro C Stand ( best on planet ) and so far these are holding up like a champ indoors and out. The double zipper was a great idea. Strobepro is Canada's best kept secret for us south of the border. Will continue to do business with them. Keith Johnson Louisville, KY
Great product, very sturdy, buying it unfilled was a must for travelling! Great Purchase
