I use a tube. A hand pump would be slightly easier to use but not required to get the suction you need. It doesn't require a lot.
My sleeves generally last over a month of daily use and only cost 2-3 dollars. Usually what ends their life is tearing on an end that spreads fast as you stretch and roll them during use, but if you catch the rip while it's small you can just cut it out with a pair of scissors. Basically sacrificing a tiny bit of material to prolong the lifespan. With good maintenance I've probably gotten two months out of one, but eventually they become either too loose, too short (as you remove rips), or develop small holes that leak air, so they definitely won't last forever.
