Note: I didn't try to get multiple keys today, but in the past have found that DVDFab often records your IP address when they have a giveaway, meaning that you need to use a VPN to change your IP address if you wanted to install the giveaway on more than one device.
As reflected in the name, DVDFab started their biz with software for copying / backing up video DVDs. While they've started to diversify, with apps like the recent GOTD, Photo Enhancer AI, DVD & Blu-ray copy / ripping is still a core part of what they do. With today's GOTD, DVDFab Blu-ray Copy, unlike some of their competition, you don't have to worry about if the disc will work, or worry about if the movie or TV show will play properly. Blu-ray DRM can jumble scenes, or quit playing part way through a movie, so not having to worry is sort of a big deal. It's also frequently updated -- videohelp[.]com/software/DVDFab/version-history
DVDFab Blu-ray Copy is just one module of DVDFab 12, so the app is a bit large at ~550MB -- if you're considering buying it, you *might* want to look at their Passkey app instead... when it's running it detects when you insert a DVD or Blu-ray disc, then bypasses the DRM. That allows you to play the disc with a regular player that otherwise would not handle the DRM, and it allows you to copy the entire disc to your hard disk. A free app, tsMuxeR, lets you copy just the main video(s), with the option to just save / use the conventional 5.1 audio, which can reduce the total file size.

DO hang on to the registration info you get today via email -- stuff happens, e.g. my GOTD copy of Photo Enhancer AI lost its registration / activation, and I was able to re-register using the same info.
FWIW... Lots of people dismiss Blu-ray discs as being too old fashioned vs. streaming, often complaining about disc storage & file size, but it's still the highest quality video you can get easily. While YMMV depending on the quality of your TV's up-scaling, I've found Blu-ray video at 1080p is typically higher quality than 4k streamed, because that streamed video has more compression to fit through the internet's pipes. OTOH I have had far too many issues with even relatively high end, name brand Blu-ray players, & even PCs stalling or stuttering during playback [because of the heavy DRM?]. I've found that playing the same files on a USB stick or hard disk eliminates the problems. After copying the disc to a hard disk, tsMuxeR copies the main video to another Blu-ray folder minus all the menus & add-on features, and using VLC for Android even plays well on a lower end Kindle HD tablet as-is [no ripping or conversion] including subs. No Blu-ray drive in your PC/laptop? Amazon sells adapters for $10-$20 [depending on sales] that let you plug in a full sized drive via USB -- it's not pretty but it works. Portable drives have gone up in price [doubled last I looked], but you *might* be able to save some cash buying a laptop drive and housing separately.
