I use android phones and have found many responsive sites to be horribly slow. Scrolling is the main thing I notice, and sometimes it is so slow ijusteave the site. Unfortunately, your site was this slow. I use an HTC One with the Dolphin browser.

I also have it set to the desktop user agent instead of android, as I would rather view the desktop site than a mobile one. With the resolution on this phone, and pretty good eyesite, I find this a much better experience. Responsive sites don't seem to have a desktop option, so I'm usually left dissatisfied with them.

It did not work on my iPhone either. A fly-in form larger than the screen slid into view and I found it difficult to interact with anything.

The page isn't responsive. The forms are. Visit ncrafts.net/a.php on your mobile device for a responsive form.

Anecdote: It looks and performs horribly on my iPad. Try it in landscape...
