I have used paint pads years ago, but they gave a smeary finish.
I find that using a small brush to do all the edges, and sticking a roller on a broom handle, takes the hassle out. The going up and down laddrs can be tiring. Stick the whole roller and tray effort into a couple of plastic shopping bags overnight so they don't dry out and don't need washing, then put another coat on next day.
