Best thing ever. I use it a lot when product testing, it's so much easier to explain when I find a bug to our developers, also works great for recording calls and doing demos or tutorials.
I use loom to create screen recordings to send to customers who use our software. It is the best way to answer customers questions about how to do something with a software product. Far superior to explaining via email or with support articles. Not only is it better, it is faster! Yes, it is faster to use Loom's chrome for a screen recording walking the customer through the process than it is to type an email instructing them. Love Loom.
