2 Pcs 33.8oz/1000ml Leg Bag Urinary Drainage Bag with 2 Pcs Catheter Leg Bag Holder, Catheter Leg Bags with Anti Reflux Valve, Urine Collection Bag with Cloth Straps for Men Woman, Easy Drain

I cannot unscrew the release valve

The holder stretches and is tighter than I would have preferred, but not to the point of discomfort. The holder doesn't breathe especially well, so it makes my leg feel warm. It itches where the bag is, even after hours of wear, which makes me wonder what the bag is made of. Speaking of the bag, it doesn't really seem to be made for the holder, it just seems to be a generic bag which is about a third too tall for the holder, so it flops out over the top. Due to how the bag is being compressed by the holder a lot of liquid capacity is lost, but I was expecting that when I ordered it. This could possibly work with a better bag, but it's hard to recommend as-is.

These urinary drainage bags work as intended, and arrived sealed & sterile. My family member likes the design of the leg bag holder. The material is soft & comfortable, and it's a great alternative than using simple straps. The best part is that the leg bag holders are washable, and can be reused.
