Well, Challenge Accepted and fulfilled. Finally found such a thing
on Amazon:
The good:
* It all breaks down quite small. The long-sides have couplers so they break down to the same length as the width.
* Relatively quick/easy to assemble and disassemble.
* Lightweight
* Cheapish - $25 when I bought mine (w/ free shipping), but list price is $45 (ouch!).
The bad:
* Cheap - I've already got a couple of popped stitches and a small tear - you have to stretch the material a bit to assemble/disassemble, leading to stress points. All the stitching is single stitched and the material is quite thin.
* There's no cross-bar mid-span, so you get a little bit of an hourglass shape (very minor)
* You pretty much have to completely disassemble it to get it into the included bag, which means all the little fittings are loose - I'm keeping mine in a ziplog inside the main bag. If the bag had been made a bit longer, you'd have been able to leave most fittings in place.
* Frame is thinner than PVC - probably wouldn't stand up to being trampled or tripped over by kids, etc.
The neutral:
* As predicted, there's a bit of a trampoline effect. Works in your favor if you're a novice player (or 2-5) years old, the target audience for this set, but not ideal if you're some sort of battle-hardened Cornhole Tournament player as the behavior will be different versus the traditional plywood targets.
* The tee fittings that fit the legs have those spring-pins so you can lock them in, but I don't see the point, since once assembled there's enough tension to keep things from moving and you have to pull the tee fitting off to get it through the sleeve anyhow.
Verdict:
With a beer in hand, it's the same old game of Cornhole/Redneck Horseshoes, but it weighs 5 pounds and packs small. The material is the biggest worry - I will definitely re-sew all the seams with a doubled reinforcing stitch, and if it continues to be a problem, I may just use these as a pattern to sew some new ones out of rip-stop nylon or something else suitably durable. It MIGHT be worth it for you to purchase depending on current price and how much time you have.
HOWEVER: I see NOTHING about this that couldn't be duplicated with a couple of yards of fabric and some PVC pipe and fittings. If you were careful about the design, you could probably even glue most of the connections except where you'd need to break it down and everything would be stronger than this product. Therefore, I say: DIY a pair of these. Just about everything about the frame construction is obvious from the picture. I'd make it such that the top/bottom pieces with the tee fittings were all just glued once inserted in the sleeves - make the long back legs remove from the tees and then just roll the material around the end-bars once the side bars were removed. I haven't figured out if it's easier to have the corners on the side-bars first then slip in the end bars, or vice-versa. Either way you're fighting the tension of the material and it's a bit of a tug of war.
