where can I find a replacement air cell for boot?

I only got the pump. Then one of the bladders sprung a leak and I couldn't find a replacement. I ended up getting a new boot. This turned out to be a really good thing as the new boot was way more comfortable. And the pump was built right into the boot.

Would this work on a small travel pillow?

Not even close ;0). Unless you're a Barbie doll. This is a small hand held air pump for a walking cast. it has 2 ends with sharp-ish points that are inserted into the aircast.

What size tubing would fit on the tip of this?

unsure - but slightly small - like the size of the ink insert in a pen maybe? I've only used mine for a walking boot to fill and release the air of the inserts. Sorry.

Universal and effective.

Definitely universal. I lost my pump for my boot and this works as well as the original one. You have to plug the hole on top with your finger in order to let the air in.

Aircast hand pump - works great!

It's exactly what it's supposed to be - and works as intended. My daughter somehow managed to lose hers, and we needed a replacement. This was less-expensive than locally-sourced and only took a few days to arrive. Good product, thanks!
