Here is my review for the Version 1 bag. Version 2 has been released and I will review it in the future. The reason I like this bag is because it's ultra light weight, at only 6.8 ounces. They are not the sturdiest quality, and needs to be near full at 10 discs inside, to remain upright, but I think it's worth the price for it's features. The version 2 bag looks to be more durable and water-resistant, as well as remain upright better. I recommend the version 1 bag if you want the lightest disc bag on the market, and don't mind that it needs to be full to stand up.

MVP Cell Bag (Black/blue) - I have to agree with the other review posted here. I picked this up for my wife thinking it was light-weight, not too big, and not very expensive despite the nice colorways and design. However, it proved to be an underwhelming bag. Despite the "rigid bottom," it actually has no structural integrity at all. Even loaded with 10+ discs it would just flop over when you set it on its base. My wife was constantly collecting and cleaning all the discs that slid out into the mud when she set her bag down the last time we played. That led me to replacing this bag with the Innova Starter bag which does stand upright, even with 3-4 discs in it. I would skip this bag and look elsewhere unless you truly want a very very lightweight, simple bag for about as cheap as you can find it, and you know what? this is the perfect bag for that! 

"Eh" is the best word I would use to describe this bag. I used it for about 20 rounds before it ripped and is now unusable. It's big enough to fit 12 discs, but the pouch on the side which is designed to hold a bottle has no drawstring, and when you pick the bag up or put it down, anything you have in that pocket will fly out and onto the ground (ask me about searching for my keys). Otherwise it's light enough that it's not a burden to carry, the strap has a good amount of length adjustment, and it's simple. There is a mesh zipper compartment under the lid which was handy for my sunglasses. It's a bit too delicate for the serious player. You get what you pay for with this entry-level small bag. I've since moved on to the infinite large bag, and I am going to be putting that through its paces as well.
