The cover arrived within two days of having placed the order, through standard delivery. It was not easy (or obvious) how to attach it to the bite valve - you need to pull quite hard to remove the bite valve from the tube and then fit the cover - they should come ready fitted when you buy your platypus! Though this is, of course, not the seller's fault. Well worth buying though, as it protects the piece that goes in your mouth from dust and dirt.
Does exactly what it should, ie protects the valve from various kinds of muck as well as preventing inadvertent leaks into car boots etc. Highly recommended item (and a good fast service from this company).
The bite Valve cover is a little dificult to fit, but once sorted its a good piece of kit. Not having to bother about if it lands on the floor when you take your rucksack off your back. Price and delivery was also very good.
