I am known by my friends as someone that loves buying equipment for any sport I try. So when I started playing disc golf last month I pretty much immediately started getting extra discs and bought this bag to carry them. So far i have a towel, light coat, water bottle, keys, phone, sunglasses/glasses and 10 discs and minis in it. It is pretty stable, not amazingly so but good enough for courses in my part of the UK as there aren't many slopes. If I keep playing I am sure I'll get a full bag but this is a great starter bag and for the price of basically 1 disc it is totally worth it.
EDIT - after having the bag only a few weeks the shoulder strap started to fray and come apart. Ace discs were awesome with their customer service and I have changed to a different bag. I have reduced this review to 3 stars to note that. Maybe I just got a bad one as until that it had felt like a really good starter bag
