Series 05210, Model SF05M-2
Arrived on time and in good condition. The count per pack is TWO, not the product description of "999999888899999". I configured the little wires into the fireworks shape like the product picture, and the "explosion" is about 20" diameter.
They're easy to put together, but it takes a few minutes to configure all those bendable little light wires into the shape you want. Time well spent, though.
The metal stakes don't seem very strong, so depending on how hard your dirt is you might want to make pilot holes with a spike, or wet the ground first. I didn't tap the top of the spike with anything, as it has to fit smoothly into another section where the panel and everything is. Didn't want to risk damage.
Maybe they came pre-charged, because they haven't gotten much sun but they're nice and bright.
I like them. They're very festive and would look great in a Christmas display.
Power and Mode buttons are on the underside of the collector panel when it's in the down position w the collector facing the sky. Those buttons are stiff, so for 1-handed Power/Mode operations while my smoke or my drink is in the other hand, I put my empty hand over the panel, wrap my fingers down around the bottom, and click upward kinda like squeezing a squeeze toy that you squeeze by squeezing.
One mode is all-on and so far that's the one I use. The others flash in various ways which might make sense in configurations other than the firework I'm using. I'm surprised there is no explosion-style mode which flashes from the inside outward, and quickly fades from the inside outward as well, like you'd expect from a firework simulation. Since these lights can flash on/off rapidly and fade pretty well, you'd think a slow-motion chase-light style firework simulation would be possible. It lost an Appearance star for that omission.
I'll enjoy them even more when it's warm enough to hang around outside.
