Swapped the valve on my pad before a weekend trip and it held firm all night. The kit came with everything for the DIY replacement and the new valve twists shut with a satisfying click.

Swapped out the old valve in about ten minutes and the new one seals tight with no leaks. The kit came with everything I needed, and my pad actually holds air through the whole night again.

My pad's old valve was leaking air all night, so this kit was a relief. The new WingLock valve seals tight now and the twist lock is easy to work with gloves on. Only gripe is the instructions are pretty thin, but a quick video search sorted it.
