Just got my kit, and some thoughts/comments:
The posting said it needed 6 AAA batteries, not included, and 2 AA batteries, included. That was a typo. They are most explicitly not included as well.
Of my three kits, I've pulled out all the EL wire 'Light Striper' to test. One of the three has a short and depending on how I move the EL wire it turns off. This is a common problem with EL wire as the corona wires are separated from the core wire by a very small phosphorous coating, and it's both a) easy to short them, and b) easy to break them. The former makes the strip go off, the latter makes the strip only work until the break.
It's easy enough to fix both - you trim the EL wire down and solder on a new connection, but it does take some practice due to the size of the corona wires.
The mounting of the inverter seems very sturdy and is much nicer than other bike-mount EL kits I've seen, and I love how the clips are designed for holding the EL on; attaching EL is always a bit of a challenge.
As for the rest... I tested one gyro flasher (turned on and waved around) and it seemed to work fine. It's fairly simple and heavy, but it'll do the job. I'd suggest putting a second one, or perhaps the writer, on the opposite side of the wheel for balance.
And the writer? I immediately took one of them apart to see how the insides were done and take lots of measurements, as I want to replace the circuit board with one that does RGB. ;) I didn't even put the batteries in to see if it worked. That said, I might... I have two more for now.
ps: Of the three EL inverters, the hum on one of the good strips was insanely loud. All EL inverters make a high-pitched hum; it's due to how they're made and to make them silent is more expensive - but it varies a lot.
pps: all of this has gaskets to help minimize water incursion, and where the EL enters also has silicon sealant. It should hold up to puddles and rain just fine, depending on how well the gaskets are seated (... mine, not so much, but that's due to me taking them apart ;)
