Great chamber! Good difficulty for so few elements!

I think this is a pretty good test chamber. It took me a little while to find the answer, even though it's pretty short. It also took me a little while to discover that the two buttons near the exit also control the two fizzlers near the entrance. I'm not sure if that's a problem that really needs to be addressed but I just thought I'd mention it. Anyway good job, I can also show my play through of it if you want.

Nice
To keep the solution pure, you may want to prevent dem cube flings.

Edit: Alternate solutions are also possible that use portal-climbing or portal-tunnelling/peeking. I consider these "dirty" methods, so don't bother preventing them. Good, challenging maps like this force us to try difficult things.
