Product review (2 stars): Spills drinks
This will not hold drinks upright. It spills everything except bottles with screw on tops. The strap should be on a swivel so the weight of the drink determines the way in hangs. The only reason I gave it 2 stars is because it seems well-constructed and I really like that it is insulated. The fact that it is fabric rather than hard plastic and would not break when folding a stroller is a huge plus for me. Because it won't hold a drink in an up right position, I have contacted the seller for a refund. I will update with the ease (or difficulty) of dealing with customer service after I get a response.
