Very Good Quality
Pros
Very well made. Expandable with extra hoops and pockets built in. I use a medium size for two tubes, tools and patch kit without expanding.
Cons
None
Other Thoughts
There is a reason I see this bag used the most on so many group rides.
Great for club rides!
Pros
Good size for carrying more than just the "bare bones".
Attachment system works great.
Cons
Would like to have some mesh side pockets inside to help organize things better.
Other Thoughts
I started with a Topeak SideKick but found it too small. I carry a spare inner tube, patch kit, multi-tool, tire levers, digital air pressure gauge, wet wipes, and some miscellaneous small stuff (zip-ties, PowerLink, etc.). This made for a VERY tight package. This is a much better size. I can also carry some sun screen, a 2nd inner tube (or a big 29r) and a power stick for my i-Phone. I use the i-Phone in a Wahoo case on my handle bars and it functions as my bike computer. Works OK, but it needs a power bump on 60 mile breakfast rides and beyond.
The bag has a mesh pocket on the inside back flap that I put my ID, cash and small items in. It would be helpful if there were some mesh panels on the sides also to organize things. It gets pretty jumbled with everything in one big compartment. There are elastic straps on the bottom. I tried to use them to hold a bike pump when I switch between my road bike and the mountain bike which does not have a frame holder. The straps were not strong enough to hold it securely; but it would probably be OK for spare tire or other items that have more bulk and stretch the straps more.
I keep the zipper in the unexpanded configuration. If unzipped, I could probably fit a compact rain shell in.
I use the loop on the back for a rear light. The attachment system works well and the bag has never come loose on rough gravel roads or trails. It is very easy to take of the bike and I do remove it when stopping for breakfast. I also bought an additional Fixer so that I can switch the bag between bikes. Fully loaded as described above I measured 1080g (2 lbs. 6 oz.). Racers and weight weenies would freak at this amount, but for my use at club rides averaging 16-18mph and centuries it suits me. Overall I think this is a very good product for my needs. Highly recommended!
Topeak Aero Seat Bag
Pros
Roomy. Have it mounted on my ebike saddle rails. Has Fat tires so the tube and tools and wrenches fit fine. Solid. Fit on rails easily and the click in slide mount was refreshing to see the thought put into it. No rattling or shake at all.
Other Thoughts
Had many saddle bags in my 50 years plus. This bag works well and is an excellent value for price.
Great quality easy to install
Pros
Great quality, heavy duty zipper. Was east to install behind my seat.
Cons
Smaller than I thought. Doesn't hold everything I need. Size is the reason I didn't give it a 5 star rating.
Small is better
Small just what I needed. Holds tube two air co2 2tire levers and small tool set. And a place to hang a light on the outside only attached to the seat not the frame
Just enough room for essentials
Topeak Large Aero Wedge Seat Bag
Pros
Style and rear opening zipper.
Cons
Top mounting straps sewed on in wrong location and barely long enough. Small or medium size might fit better and be more stable.
Great Product
Pros
This is my second Topeak bag. I bought the medium size for another bike. Like the smaller bag the large is Very well made. Secure easy to use mounting system. Fits perfectly on a large frame mountain bike with seat adjusted for 5'11" rider.
Maybe a little big for smaller frame bikes and smaller riders.
Easily holds 29er tube, multi tool, tire tools, tire inflator, rag, and some other small items. Perfect mount for light on rear of bike.
Cons
Your hardest job will be figuring out what size is best fit for your needs and your bike

Modern Bike was fast and easy to purchase from
High quality product
Pros
The bag is very well made. Fits on the bike very very well and secures very well. I struggled on decision between medium and large size. The medium using the expansion zipper is just right size for spare tube, multi tool, tire levers, small tier pump along with COz inflator and small rag. It's a very snug fit but everything fits. I ordered a large bag a few weeks latter for my mountain bike that I use for more remote riding and carry a few more items easily.
I'm a 65 year old recreational rider and these bags are the best I have seen.
Cons

EXCELLENT BAG !!! AAA all the way !!!
Pros
LOTS of ROOM NICE QUICK CONNECT EXCELLENT DESIGN
Cons
This applies to any bag or type of mounting. In a dark area CHECK where your taillight's focal point is. I bet you'll see it is on the ground. On a bag using a clothes clip mount that will usually focuses the light's "beam" DOWN to about 5 to 10 feet on the ground behind the rear wheel, if not less- that is NO GOOD !!! Personally I sewed another 1" wide nylon strap 3 1/2" higher on this bag to get my Cateye Omni 5 tail light up higher for better visibility. I use a torch (KEEP THE FLAME MOVING!!!) to heat the clothes clip at the fold & open it up. I put a VERY SLIGHT twist in the clip to the riders left because we ride over to the right side of the road. Take your time. You want the "beam" to be focused in the drivers eyes. On level ground say 4 to 5 feet off the ground at about 40 to 60 feet. At 300 feet it is in a tractor trailers
drivers eyes too. Whether it is a car or a tractor trailers NOW you will be seen at a GREAT DISTANCE --- DAY OR NIGHT !
Oh yea, in Europe it is illegal to run a bicycle tail light on the "steady" mode, it MUST be flashing or blinking. Personally I believe we are much more visible with a flashing mode AND your battery will last a WHOLE LOT LONGER, TOO!!!

ENJOY!!!
Great purchase
Pros
Size, shape, material, good quality
Cons
None
Excellent Seat Bag
Pros
The medium size I bought carries what I need. Without expanding, it's a bit tight for much else. Due the the shape of this bag, this size works best with a higher seat post. Loop on the back for mounting a taillight is a big plus.
Cons
None.
Nicely built, but a little odd, and way too small
Pros
Appears well constructed and mounts easily to seat
Cons
I found this product way too small to be of much use. The way in which it opens is also a little awkward.
Other Thoughts
I think the wedge shape is a little gimmicky, and takes away from usable space. The model I purchased has about enough room for a compact tube and either a wallet or a cell phone, but not all three. I've since switched back to a more conventional seat bag, which has a lot more usable interior space, with about the same exterior footprint.
Small Indeed
