Got home and inspected the haul:
Dayglo jersey - fits well, the zippy pocket (zip along the top of the pocket, across your back) at the back seems easy enough to use, and it's bright!
Red jersey - Nice features like a flap to cover the zip / protect your neck when done right up. The pocket zips up the sides, which means I can mount a fibre-flare light across the small of my back. Thumb holes in the cuffs are too small, and there's too much fabric in the forearms - the cut is all wrong, but not enough to flap. A quick ride out in this and it was comfy, warm, but not overly so. The tail of the jersey stayed in place just fine.
Reflective strips+LEDs - Tiny lights, and they're quite dim. Some of them look a little brighter than others, as though a couple of the bands got turned on in transit, but none of them are massively bright. However, as there are unlit roads around me these will still be useful for cycling or walking anywhere at night. Better than nothing, especially at the price.
Winter gloves - fit is ok around the wrist and palm, but the set I have seem to be the witch fitting, as they're an inch too long in each of the fingers. However, they'll do for now.
Also got a set of the waterproof trousers, and the bike stand, but haven't unpacked those yet. All in all, nothing's perfect, but I'm happy with it and won't be taking it back.
