Good, but not amazing; the voice gets a little annoying after a couple of songs, and the lyrics aren't anything mind-blowing... but it works for a little while.
Crystal Stilts do one thing really really well: dark reverb-y post-punk. Like a bunch of Raveonettes that are just never going to sing about sunshine, Crystal Stilts hammer out catchy, dark pop songs like it ain't nobody's business. And there's a shit-ton of reverb. Pay attention to these guys in the future.
