Just out of pure curiosity; there's a handful on AliExpress hovering in the range of $30 that go out of the way to hide the EZ-Flash name on the product images. No idea if they're trying to hide from Nintendo's potential legal actions or if they're just bad clones (at least one of them uses the Wowolink name, which the EZ-Flash team specifically denounced as unofficial).
Some of the reviews also mention issues with the 1.78 or 2.00 kernels, but never go into real detail; it's possible the EZ-Flash team added some form of anti-clone code to the kernel.
Considering picking one up to test alongside a cart from the 'official' reseller list to see if either feels or performs notably better. Either way, the last GBA cart I bought was one of the $10 128M Fire Linkers from DealExtreme a decade ago, so it'd be hard to do much worse.
