Kobo is an eBook store with their own eReaders, like Amazon Kindle or Barnes and Noble Nook. You can use Kobo with one of their devices, or you can use an app on your phone or tablet. Like Amazon and Barnes and Noble though, they want you to only read the books through their apps or devices.

My opinion on Kobo is that it's pretty good. They do daily deals where they massively discount books for 24 hours. I've gotten some good deals out of it.

I have a kobo reader that I use for DRM free books...so they're legit - trying to match Amazon's hold on the ebook market I think

Kobo puts DRM in their eBooks when publishers demand it, depends on the book, dunno about these particular ones.

I have a Kobo e-reader so I can't say if these books are DRM free or not. I'm not sure when HumbleBundle started doing this but this isn't the first book bundle they've done through Kobo.

would be great to know if it comes with drm. I don't have a kobo. It says 'use on any device' on the humble page...does that mean no drm?
