[EX Q]: These things are cheap cheap cheap. The plastic is terrible, the mold they used is terrible, the straws literally fall apart inside the bottle. I suggest getting legit ones from a supply company.
[EX A]: negative

[EX Q]: This fits perfect and firm with the Velcro, so its fully adjustable. Feels light on the legs, you get used to it after wearing it for a while. Fits my 9mm snug. The outer fabric material is smooth so it doesn't rub against your pants.
[EX A]: positive

[EX Q]: Perfect replacement knobs for a recent kitchen remodel. Instead of paying nearly $3 per knob, these were less than $1 each, and seem to be of comparable quality.
[EX A]:
positive
