The price is very cheap for what you get! I've used this service many times in my life as an editor or director of photography (DP). It's easy enough that even inexperienced people can use it effectively without too much trouble - if they have basic editing skills at least; but there are plenty tutorials available online so all levels should be able to make good images using these tools easily. You're limited by camera quality/resolution when shooting stock footage because cameras usually don't give great results from low resolution sources like SD cards etc., however deathtoStock gives us options where we could shoot high res video directly off our phones which would otherwise not possible due to storage limitations.
