I think this is a great small bag. I own (and have owned) many bags over the years, and although my favorite bag that I currently own is a Pound Rufus, I wanted to really find a good small bag from travel or when I just don't need that many discs. 

IMO the best small bags available would be the Pound Vagabond and the Revolution Mini Deluxe with Quad Straps (I own both). But the price point for those bags, are quite a bit more than this one. I think for the price and the storage, this is a really great option. 

I am able to put a 24 oz water bottle no problem in the water bottle holder, and can easy put my wallet and cell phone in the pockets. I put 9 discs in the main compartment and then 1 disc in the putter pocket. I would say that at times it can fall over, but I can usually find a way to low it down properly and not have that issue. 

If you want a bag that can just hold the basics, and feel comfortable I think this is a great option. I actually wasn't familar with this company before I heard it mentioned in the Infinite Discs newsletter and I am glad I purchased one. 

I love this bag.  It is what I have been looking for this past year of playing.  It appeals to my lazy side in that I have access to all of my discs and can leave it open, but limits me to 7-10 discs, which is more helpful when learning to play...There are thre sleeves along the inside back to place discs, and the rest go in the front/bottom.  All discs face you as you look at the bag.  Yes, because it is a small bag and the way the discs fit in, the bag does not stand upright when you set it down, but my discs don't fall out when it flops over.  I also love the putter pouch on the inside of the closure flap.  The carry handle is double nylon webbing with a padded handle.
 

The water bottle holder will fit a 27 oz. Kleen Kanteen or 20 oz. (or taller) Smart water bottle.  Neither bottle has fallen out.  I carry a small bug spray and a sharpie in the side pocket, as well as my retriever (held with a carabiner attached to the top carry handle).  The front pocket is large enough for a phone, keys, and handwarmer packets.  

The backpack straps are padded and very comfortable.  They have rings on them so you can attach a towel or clay bag.  The bag itself is padded, there is padding on the back, and the fabric is durable and assembled well.  There is some kind of nylon fabric covering the bottom for what looks like durability.  This bag is smaller, about the height of the Trooper if you cut the top compartment off, but extremely comfortable to carry.  It's a great beginner/small bag.
