I bought a 2-gallon compressor a while back, mostly to facilitate tubeless installs, just before this wave of products came to market. It works, but I hate it. It's so noisy.
Also, the price went up quickly when I had to buy a hose and a chuck to make the system work.
Considering I use it primarily to mount tires, I'd be happy to have a lighter, smaller, quieter, and more portable single-use piece.
