The ease of use, how simple it is to create amazing videos for our clients! I love that we can edit them all in one place as well so there are no extra costs or time spent editing each individual clip if you have multiple people speaking at once (which happens often). Sometimes when using some programs like this they don't always save correctly after an update which causes problems but other than those minor hiccups everything has been smooth sailing thus far!! We've used many different companies over my career including Adobe Premiere Pro CC 2018 & After Effects CS6-CC 2019 - none compare to shakrs simplicity nor their quality/price ratio compared to others out here making similar products. As above mentioned sometimes things may not be saved properly from versioning issues however these seem rare now since updating recently though still could happen occasionally depending upon what program being edited etc.. Overall very happy customer who would highly recommend anyone looking.
