Endura use some cheap weak generic version of the press stud, all mine and everyone I know who has 'em has the waistband pop open all the time (and no I'm not chunky, breathing in is enough to do it).
+1000 for gloves with linings that come out with your hand, got some £30 Enduras (possibly a pattern here) that do this, like cheap market stall winter gloves did when I was a kid.
Lezyne pumps are brilliant.
Elite Sior bottle cage. Holds bottle so tightly I was worried I'd strip the bosses out the frame.
Some green michelin DH/FR innertube I bought in Morzine; punctured first ride and found whatever it was made out of patches wouldnt stick to it, so it got binned on its first day
Aldi track pump. What air did go in on the downstroke got sucked out on the upstroke. Head such a tight fit you risked tearing your valve off with it. And on the 3rd attempt at using it the handle came off. No quibble return policy thankfully.
