It's hard to configure browsers:you need to use other linux distro to do it. Expect hardware support problems. On my Asus T100TA it was constantly beeping after booting. No UEFI support (but you can add it yourself if you remix their kiosk iso). Need to pay for updates. No easy way to install on a HDD but it is possible after some work - frugal install and configure bootloader on your own. They think it's more secure to boot from USB, I don't get it. Generally It's not good but still best option available for free users. Would love to see a new kiosk distro with easy browser updates and browser/network configuration without being forced to reinstall every time or using other linux to remix settings.
